commit 6ca653e3f7 upstream.
The Quanta NL3 laptop has both a headphone output jack and a headset
jack, on the right edge of the chassis.
The pin information suggests that both of these are at the Front.
The PulseAudio is confused to differentiate them so one of the jack
can neither get the jack sense working nor the audio output.
The ALC269_FIXUP_LIFEBOOK chained with ALC269_FIXUP_QUANTA_MUTE can
help to differentiate 2 jacks and get the 'Auto-Mute Mode' working
correctly.

commit 13be30f156 upstream.
This Acer Veriton N4640G/N6640G/N2510G desktops have 2 headphone
jacks(front and rear), and a separate Mic In jack.
The rear headphone jack is actually a line out jack but always silent
while playing audio. The front 'Mic In' also fails the jack sensing.
Apply the ALC269_FIXUP_LIFEBOOK to have all audio jacks to work as
expected.

There are a few places that call round{up|down}_pow_of_two() with the
value zero, and this causes undefined behavior warnings. Avoid
calling those macros if such a nonsense value is passed; it's a minor
optimization as well, as we handle it as either an error or a value to
be skipped, instead.

commit c72b9bfe0f upstream.
This change could fix 2 issues on this machine:
- the bass speaker's output volume can't be adjusted, that is because
the bass speaker is routed to the DAC (Nid 0x6) which has no volume
control.
- after plugging a headset with vol+, vol- and pause buttons on it,
press those buttons, nothing happens, this means those buttons
don't work at all. This machine has alc287 codec, need to add the
codec id to the disable/enable_headset_jack_key(), then the headset
button could work.
The quirk of ALC285_FIXUP_THINKPAD_HEADSET_JACK could fix both of these
2 issues.

It seems that the HD-audio clear and reconfig sysfs don't work any
longer after the recent driver core change. There are multiple issues
around that: the linked list corruption and the dead device handling.
The former issue is fixed by another patch for the driver core itself,
while the latter patch needs to be addressed in HD-audio side.
This patch corresponds to the latter, it recovers those broken
functions by replacing the device detach and attach actions with the
standard core API functions, which are almost equivalent with unbind
and bind actions.

commit b08221c40f upstream.
Recently we met a touchscreen problem on some Thinkpad machines, the
touchscreen driver (i2c-hid) is not loaded and the touchscreen can't
work.
An i2c ACPI device with the name WACF2200 is defined in the BIOS, with
the current rule in matching_id(), this device will be regarded as
a PNP device since there is WACFXXX in the acpi_pnp_device_ids[] and
this PNP device is attached to the acpi device as the 1st
physical_node, this will make the i2c bus match fail when i2c bus
calls acpi_companion_match() to match the acpi_id_table in the i2c-hid
driver.
WACF2200 is an i2c device instead of a PNP device, after adding the
string length comparing, the matching_id() will return false when
matching WACF2200 and WACFXXX, and it is reasonable to compare the
string length when matching two IDs.

This reverts commit 8a66790b78.
Switching this function to AE_CTRL_TERMINATE broke the documented
behaviour of acpi_dev_get_resources() - AE_CTRL_TERMINATE does not, in
fact, terminate the resource walk because acpi_walk_resource_buffer()
ignores it (specifically converting it to AE_OK), referring to that
value as "an OK termination by the user function". This means that
acpi_dev_get_resources() does not abort processing when the preproc
function returns a negative value.

commit 7482c5cb90 upstream.
The idea behind acpi_pm_set_bridge_wakeup() was to allow bridges to
be reference counted for wakeup enabling, because they may be enabled
to signal wakeup on behalf of their subordinate devices and that
may happen for multiple times in a row, whereas for the other devices
it only makes sense to enable wakeup signaling once.
However, this becomes problematic if the bridge itself is suspended,
because it is treated as a "regular" device in that case and the
reference counting doesn't work.
For instance, suppose that there are two devices below a bridge and
they both can signal wakeup. Every time one of them is suspended,
wakeup signaling is enabled for the bridge, so when they both have
been suspended, the bridge's wakeup reference counter value is 2.
Say that the bridge is suspended subsequently and acpi_pci_wakeup()
is called for it. Because the bridge can signal wakeup, that
function will invoke acpi_pm_set_device_wakeup() to configure it
and __acpi_pm_set_device_wakeup() will be called with the last
argument equal to 1. This causes __acpi_device_wakeup_enable()
invoked by it to omit the reference counting, because the reference
counter of the target device (the bridge) is 2 at that time.
Now say that the bridge resumes and one of the device below it
resumes too, so the bridge's reference counter becomes 0 and
wakeup signaling is disabled for it, but there is still the other
suspended device which may need the bridge to signal wakeup on its
behalf and that is not going to work.
To address this scenario, use wakeup enable reference counting for
all devices, not just for bridges, so drop the last argument from
__acpi_device_wakeup_enable() and __acpi_pm_set_device_wakeup(),
which causes acpi_pm_set_device_wakeup() and
acpi_pm_set_bridge_wakeup() to become identical, so drop the latter
and use the former instead of it everywhere.

The gspca driver leaks memory when a probe fails. gspca_dev_probe2()
calls v4l2_device_register(), which takes a reference to the
underlying device node (in this case, a USB interface). But the
failure pathway neglects to call v4l2_device_unregister(), the routine
responsible for dropping this reference. Consequently the memory for
the USB interface and its device never gets released.
This patch adds the missing function call.

Although this bug was technically introduced from the beginning, that
is commit 3a0af8fd61 ("bpf: BPF for lightweight tunnel infrastructure"),
at that time call_rcu() had to be call_rcu_bh() to match the RCU context.

Namespaced file capabilities were introduced in 8db6c34f1d .
When userspace reads an xattr for a namespaced capability, a
virtualized representation of it is returned if the caller is
in a user namespace owned by the capability's owning rootid.
The function which performs this virtualization was not hooked
up if CONFIG_SECURITY=n. Therefore in that case the original
xattr was shown instead of the virtualized one.
To test this using libcap-bin (*1),
$ v=$(mktemp)
$ unshare -Ur setcap cap_sys_admin-eip $v
$ unshare -Ur setcap -v cap_sys_admin-eip $v
/tmp/tmp.lSiIFRvt8Y: OK
"setcap -v" verifies the values instead of setting them, and
will check whether the rootid value is set. Therefore, with
this bug un-fixed, and with CONFIG_SECURITY=n, setcap -v will
fail:
$ v=$(mktemp)
$ unshare -Ur setcap cap_sys_admin=eip $v
$ unshare -Ur setcap -v cap_sys_admin=eip $v
nsowner[got=1000, want=0],/tmp/tmp.HHDiOOl9fY differs in []
Fix this bug by calling cap_inode_getsecurity() in
security_inode_getsecurity() instead of returning
-EOPNOTSUPP, when CONFIG_SECURITY=n.

[ Upstream commit 135b4957ea ]
$(error-if,...) is expanded to an empty string. Currently, it relies on
eval_clause() returning xstrdup("") when all attempts for expansion fail,
but the correct implementation is to make do_error_if() return xstrdup("").

[ Upstream commit 48f68de00c ]
Two clock divider tables are missing sentinel at the end. Effect of that
is that clock framework reads past the last entry. Fix that with adding
sentinel at the end.
Issue was discovered with KASan.

The "vq" struct is added to the "vdev->vqs" list prematurely. If we
encounter an error later in the function then the "vq" is freed, but
since it is still on the list that could lead to a use after free bug.

[ Upstream commit 1f0f1e80fd ]
When there are other PWM controllers enabled along with pwm-lp3943,
pwm-lp3942 is failing to probe with -EEXIST error. This is because
other PWM controllers are probed first and assigned PWM base 0 and
pwm-lp3943 is requesting for 0 again.
In order to avoid this, assign the chip base with -1, so that it is
dynamically allocated.
