[ Upstream commit 856a0a6e2d ]
This is caused by dereferencing 'dev_data' after put_device() in
the telem_device_remove() function.
This patch just moves the put_device() down a bit to avoid this
issue.

commit 6ae01050e4 upstream.
Use our default values when wrong module-parameters are given, instead of
refusing to load. Refusing to load leaves the fan at the BIOS default
setting, which is "Off". The CPU's thermal throttling should protect the
system from damage, but not-loading is really not the best fallback in this
case.
This commit fixes this by re-setting module-parameter values to their
defaults if they are out of range, instead of failing the probe with
-EINVAL.

This commit fixes the potential deadlock caused by the console Rx

the lock.

[ Upstream commit 60d1509533 ]
We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts peaq-wmi driver to use the
polling mode of standard input devices and removes dependency on
INPUT_POLLDEV.
Because the new polling coded does not allow peeking inside the poller
structure to get the poll interval, we change the "debounce" process to
operate on the time basis, instead of counting events.
We also fix error handling during initialization, as previously we leaked
input device structure when we failed to register it.

commit f3e4f3fc8e upstream.
The AML code implementing the WMI methods creates a variable length
field to hold the input data we pass like this:
CreateDWordField (Arg1, 0x0C, DSZI)
Local5 = DSZI /* \HWMC.DSZI */
CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN)
If we pass 0 as bios_args.datasize argument then (Local5 * 0x08)
is 0 which results in these errors:
[ 71.973305] ACPI BIOS Error (bug): Attempt to CreateField of length zero (20190816/dsopcode-133)
[ 71.973332] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529)

And in our HPWMI_WIRELESS2_QUERY calls always failing. for read commands
like HPWMI_WIRELESS2_QUERY the DSZI value is not used / checked, except for
read commands where extra input is needed to specify exactly what to read.
So for HPWMI_WIRELESS2_QUERY we can safely pass the size of the expected
output as insize to hp_wmi_perform_query(), as we are already doing for all
other HPWMI_READ commands we send. Doing so fixes these errors.

commit 16245db148 upstream.
The HP WMI calls may take up to 128 bytes of data as input, and
the AML methods implementing the WMI calls, declare a couple of fields for
accessing input in different sizes, specifycally the HWMC method contains:
CreateField (Arg1, 0x80, 0x0400, D128)
Even though we do not use any of the WMI command-types which need a buffer
of this size, the APCI interpreter still tries to create it as it is
declared in generoc code at the top of the HWMC method which runs before
the code looks at which command-type is requested.
This results in many of these errors on many different HP laptop models:
[ 14.459261] ACPI Error: Field [D128] at 1152 exceeds Buffer [NULL] size 160 (bits) (20170303/dsopcode-236)

This commit increases the size of the data element of the bios_args struct
to 128 bytes fixing these errors.

For APIC case of interrupt we don't fail a ->probe() of the driver,
which makes kernel to print a lot of warnings from the children.
We have two options here:
- switch to platform_get_irq_optional(), though it won't stop children
to be probed and failed
- fail the ->probe() of i2c-multi-instantiate
Since the in reality we never had devices in the wild where IRQ resource
is optional, the latter solution suits the best.

Here is the big driver core update for 5.4-rc1.
There was a bit of a churn in here, with a number of core and OF
platform patches being added to the tree, and then after much discussion
and review and a day-long in-person meeting, they were decided to be
reverted and a new set of patches is currently being reviewed on the
mailing list.
Other than that churn, there are two "persistent" branches in here that
other trees will be pulling in as well during the merge window. One
branch to add support for drivers to have the driver core automatically
add sysfs attribute files when a driver is bound to a device so that the
driver doesn't have to manually do it (and then clean it up, as it
always gets it wrong).
There's another branch in here for generic lookup helpers for the driver
core that lots of busses are starting to use. That's the majority of
the non-driver-core changes in this patch series.
There's also some on-going debugfs file creation cleanup that has been
slowly happening over the past few releases, with the goal to hopefully
get that done sometime next year.
All of these have been in linux-next for a while now with no reported
issues.

v5.4 kernel cycle.
Core changes:
- Support hierarchical GPIO irqchips. We now have three
consumers that can use this: Intel IXP4xx, ThunderX and
Qualcomm SPMI GPIO (in the pinctrl subsystem). The support
code has been long in the making and hashed out so it should
be easily adaptable for all hierarchical irqchip parents.
The code only gets compiled in if hierarchical irqchip
is used at the topmost irq controller at least, as the
hierarchical irqchip requires strict hierarchy all the
way up in the system.
- Determine the need for a "valid_mask" for GPIO lines on the
gpio_chip and conversely for the "valid_mask" for the GPIO
interrupt chip interrupt lines by looking for a
.init_valid_mask() callback in the main chip or GPIO interrupt
chip respectively. Allocate it with bitmap_alloc().
- Isolate the device tree/open firmware GPIO description code
out in its own file properly.
- Isolate the ACPI GPIO description code out in its own file
properly.
- Drop a whole lot of #ifdef:s in the main includes: it does
not hurt to keep the include items around, and we get
quicker and clearer compile failures if the appropriate
kernel symbols are not selected for drivers.
New/deleted drivers:
- New driver for Aspeed SGPIO.
- The KS8695 driver is deleted as the platform gets deleted
from arch/arm in this kernel cycle.
- The Cirrus Logic Madera driver now supports CS47L92 and
CS47L15.
- The Freescale MPC8xxx now supports LS1028A and LS1088A.
Driver improvements:
- We pass the GPIO irqchip intialization by directly filling
in the struct instead of using set-up functions (the new
way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed,
ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.
Out-of-band changes:
- Fix a GPIO header inclusion in Unicore - no response from
maintainer.
- Drop FMC subsystem from MAINTAINERS - was deleted in the
GPIO tree last cycle so let's mop up the shards.

When driver has been switched to use ACPI battery API in the commit
7973353e92 ("Refactor charge threshold to use the battery hooking API")
it makes it implicitly dependent to a corresponding kernel configuration
option.
Make this dependency explicit in Kconfig.

Allow to poll on the cros_ec device to receive the MKBP events.
The /dev/cros_[ec|fp|..] file operations now implements the poll
operation. The userspace can now receive specific MKBP events by doing
the following:
- Open the /dev/cros_XX file.
- Call the CROS_EC_DEV_IOCEVENTMASK ioctl with the bitmap of the MKBP
events it wishes to receive as argument.
- Poll on the file descriptor.
- When it gets POLLIN, do a read on the file descriptor, the first
queued event will be returned (using the struct
ec_response_get_next_event format: one byte of event type, then
the payload).
The read() operation returns at most one event even if there are several
queued, and it might be truncated if the buffer is smaller than the
event (but the caller should know the maximum size of the events it is
reading).
read() used to return the EC version string, it still does it when no
event mask or an empty event is set for backward compatibility (despite
nobody really using this feature).
This will be used, for example, by the userspace daemon to receive and
treat the EC_MKBP_EVENT_FINGERPRINT sent by the FP MCU.

Since the rpmsg_endpoint is created before probe is called, it's
possible that a host event is received during cros_ec_register, and
there would be some pending work in the host_event_work workqueue while
cros_ec_register is called.
If cros_ec_register fails, when the leftover work in host_event_work
run, the ec_dev from the drvdata of the rpdev could be already set to
NULL, causing kernel crash when trying to run cros_ec_get_next_event.
Fix this by creating the rpmsg_endpoint by ourself, and when
cros_ec_register fails (or on remove), destroy the endpoint first (to
make sure there's no more new calls to cros_ec_rpmsg_callback), and then
cancel all works in the host_event_work workqueue.

After changing the valid_mask for the struct gpio_chip
to detect the need and presence of a valid mask with the
presence of a .init_valid_mask() callback to fill it in,
we augment the gpio_irq_chip to use the same logic.
Switch all driver using the gpio_irq_chio valid_mask
over to this new method.
This makes sure the valid_mask for the gpio_irq_chip gets
filled in when we add the gpio_chip, which makes it a
little easier to switch over drivers using the old
way of setting up gpio_irq_chip over to the new method
of passing the gpio_irq_chip along with the gpio_chip.

Commit 871f1f2bcb ("platform/x86: intel_int0002_vgpio: Only implement
irq_set_wake on Bay Trail") removed the irq_set_wake method from the
struct irq_chip used on Cherry Trail, but it did not set
IRQCHIP_SKIP_SET_WAKE causing kernel/irq/manage.c: set_irq_wake_real()
to return -ENXIO.
This causes the kernel to no longer see PME events reported through the
INT0002 device as wakeup events. Which e.g. breaks wakeup by the (USB)

The validity of address PMC_BASE_ADDR_DEFAULT (i.e., 0xFE000000) is not

There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.
In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:
- Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
- Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
driver from include/linux/mfd/cros_ec.h to a new file
include/linux/platform_data/cros_ec_proto.h
- Update all the drivers with the new includes, so
- Drivers that only need to know about the protocol include
- linux/platform_data/cros_ec_proto.h
- linux/platform_data/cros_ec_commands.h
- Drivers that need to know about the cros-ec mfd device also include
- linux/mfd/cros_ec.h

That's a driver to talk with the ChromeOS Embedded Controller via a
miscellaneous character device, it creates an entry in /dev for every
instance and implements basic file operations for communicating with the
Embedded Controller with an userspace application. The API is moved to
the uapi folder, which is supposed to contain the user space API of the
kernel.
Note that this will replace current character device interface
implemented in the cros-ec-dev driver in the MFD subsystem. The idea is
to move all the functionality that extends the bounds of what MFD was

An MFD is a device that contains several sub-devices (cells). For instance,
the ChromeOS EC fits in this description as usually contains a charger and
can have other devices with different functions like a Real-Time Clock,
an Audio codec, a Real-Time Clock, ...
If you look at the driver, though, we're doing something odd. We have
two MFD cros-ec drivers where one of them (cros-ec-core) instantiates
another MFD driver as sub-driver (cros-ec-dev), and the latest
instantiates the different sub-devices (Real-Time Clock, Audio codec,
etc).

|
|___ mfd-cellB (cros-ec-dev)
|__ mfd-cell0
|__ mfd-cell1

The problem that was trying to solve is to describe some kind of topology for
the case where we have an EC (cros-ec) chained with another EC
(cros-pd). Apart from that this extends the bounds of what MFD was
designed to do we might be interested on have other kinds of topology that
can't be implemented in that way.
Let's prepare the code to move the cros-ec-core part from MFD to
platform/chrome as this is clearly a platform specific thing non-related
to a MFD device.

Commit 10a08fd65e ("ACPI: PM: Set up EC GPE for system wakeup from
drivers that need it") assumed that the EC GPE would only need to be
set up for system wakeup if either the intel-hid or the intel-vbtn
driver was in use, but that turns out to be incorrect. In particular,
on ASUS Zenbook UX430UNR/i7-8550U, if the EC GPE is not enabled while
suspended, the system cannot be woken up by opening the lid or
pressing a key, and that machine doesn't use any of the drivers
mentioned above.
For this reason, always set up the EC GPE for system wakeup from
suspend-to-idle by setting and clearing its wake mask in the ACPI
suspend-to-idle callbacks.

Both intel-hid and intel-vbtn set a wakeup_mode flag causing them
to behave in a special way during system suspend and while suspended
in their "prepare" PM callbacks and clear it in their "resume" PM
callbacks. That may cause the wakeup_mode flag to remain set after
a system suspend failure (if some other driver's "suspend" callback
returns an error before the "suspend" callback of either intel-hid
or intel-vbtn is invoked).
After commit 10a08fd65e ("ACPI: PM: Set up EC GPE for system wakeup
from drivers that need it") that also affects the "wakeup mask" bit
of the EC GPE, which may not be cleared after a failing system
suspend.
Fix this issue by adding "complete" PM callbacks to intel-hid and
intel-vbtn to clear the wakeup_mode flag and the "wakeup mask" bit
of the EC GPE if they have not been cleared earlier.

Previously, asus-wmi was using the AGFN interface and FAN_CTRL device
for CPU fan control. However, this code has been found to be not fully
working on some recent products, and having checked the spec, these
interfaces are marked as being removed from future products currently
in development.
The replacement appears to be the CPU_FAN device, added in spec version
8.3 (March 2014) and present on many modern Asus laptops.
Add support for this device, and use it whenever it is detected.
The older approach based on AGFN and FAN_CTRL is used as a fallback
on products that do not have such device.
Other than switching between automatic and full speed, there is
no fan speed control through this new interface.

The asus-wmi driver currently uses the "AGFN" interface and
the FAN_CTRL device for fan control. According to the spec, this
interface is very dated and marked as pending removal from products
currently in development.
Clean up the way that the AGFN fan is detected and handled, also
preparing the driver for the introduction of an alternate fan
control method needed to support recent Asus products.
Not anticipating further development of this interface, simplify
the code by dropping any notion of being able to control multiple
AGFN fans (this was already limited to just a single fan through only
exposing a single fan in sysfs).
Check for the presence of AGFN fans at probe time, simplifying the code
flow in asus_hwmon_sysfs_is_visible().

The APU3+ boards have two SIM sockets, while only one of them
can be routed to the mpcie slots at a time. Selection is done
via simswap gpio.
We currently don't have a fitting subsystem for those cases yet,
so just wire it up to a LED for the time being. While this isn't
really semantically correct, it's a good compromise.

On APUx we have also mpcie2/mpcie3 reset pins. To make it possible to reset
the ports from the userspace, add the definition to this platform
device. The gpio can then be exported by the legancy gpio subsystem to
toggle the mpcie reset pin.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array.
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.

The EC GPE needs to be set up for system wakeup only if there is a
driver depending on it, either intel-hid or intel-vbtn, bound to a
button device that is expected to wake up the system from sleep (such
as the power button on some Dell systems, like the XPS13 9360). It
doesn't need to be set up for waking up the system from sleep in any
other cases and whether or not it is expected to wake up the system
from sleep doesn't depend on whether or not the LPS0 device is
present in the ACPI namespace.
For this reason, rearrange the ACPI suspend-to-idle code to make the
drivers depending on the EC GPE wakeup take care of setting it up and
decouple that from the LPS0 device handling.
While at it, make intel-hid and intel-vbtn prepare for system wakeup
only if they are allowed to wake up the system from sleep by user
space (via sysfs).
[Note that acpi_ec_mark_gpe_for_wake() and acpi_ec_set_gpe_wake_mask()
are there to prevent the EC GPE from being disabled by the
acpi_enable_all_wakeup_gpes() call in acpi_s2idle_prepare(), so on
systems with either intel-hid or intel-vbtn this change doesn't
affect any interactions with the hardware or platform firmware.]

kmemdup is introduced to duplicate a region of memory in a neat way.
Rather than kmalloc/kzalloc + memcpy, which the programmer needs to
write the size twice (sometimes lead to mistakes), kmemdup improves
readability, leads to smaller code and also reduce the chances of mistakes.
Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.
