The method struct pci_error_handlers.error_detected() is defined and
documented as taking an 'enum pci_channel_state' for the second argument,
but most drivers use 'pci_channel_state_t' instead.
This 'pci_channel_state_t' is not a typedef for the enum but a typedef for
a bitwise type in order to have better/stricter typechecking.
Consolidate everything by using 'pci_channel_state_t' in the method's
definition, in the related helpers and in the drivers.
Enforce use of 'pci_channel_state_t' by replacing 'enum pci_channel_state'
with an anonymous 'enum'.
Note: Currently, from a typechecking point of view this patch changes
nothing because only the constants defined by the enum are bitwise, not the
enum itself (sparse doesn't have the notion of 'bitwise enum'). This may
change in some not too far future, hence the patch.

To ensure that the octeon MDIO driver has been loaded, the Cavium
ethernet drivers reference a dummy symbol in the MDIO driver. This
forces it to be loaded first. And this symbol has not been cleanly
implemented, resulting in warnings when build W=1 C=1.
Since device tree is being used, and a phandle points to the PHY on
the MDIO bus, we can make use of deferred probing. If the PHY fails to
connect, it should be because the MDIO bus driver has not loaded
yet. Return -EPROBE_DEFER so it will be tried again later.
Additionally, add a MODULE_SOFTDEP() to give user space a hint as to
what order it should load the modules.

vchi_msg_dequeue() provides the same functionality as vchi_msg_hold()
except it copies the message data as opposed to the later which provides
the data in place.
The copying is done on a local variable, so there is no need to keep the
message out the function's bounds, so use vchi_msg_hold() instead.

The idea behind struct vchi_service_handle is to create an opaque handle
to struct shim_service. This can be achieved by doing a forward
declaration of struct shim_service, which will avoid unwarranted casts
and pointer play.
Ultimately as a rename is due all over the vchi user space, rename
struct shim_service into struvt vchi_service, which is more consistent
with the rest of the exposed API.

There already is a function that covers most of the functionality
vchi_msg_peek() provides: vchi_msg_hold(). The main difference being
that the later removes the message from vchu's queue while the other
does it later on, while releasing the message.
There are no users of this function that can't be trivially converted to
vchi_msg_hold(). So, for the sake of removing duplicate code, get rid of
vchi_msg_peek().
Note that the opposite change could be performed as well. But
vchi_msg_peek()'s implementation was deemed less robust as messages have
to be released in order.

mmal-vchiq is a reimplementation of the userland library for MMAL.
When getting a parameter, the client provides the storage and
the size of the storage. The VPU then returns the size of the
parameter that it wished to return, and as much as possible of
that parameter is returned to the client.
The implementation previously only returned the size provided
by the VPU should it exceed the buffer size. So for parameters
such as the supported encodings list the client had no idea
how much of the provided storage had been populated.

The MMAL client_component field is used with the event
mechanism to allow the client to identify the component for
which the event is generated.
The field is only 32bits in size, therefore we can't use a
pointer to the component in a 64 bit kernel.
Component handles are already held in an array per VCHI
instance, so use the array index as the client_component handle
to avoid having to create a new IDR for this purpose.

The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().
struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).
It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.
To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.

deletes a lot of duplicate definitions plus many unused ones.
Non obvious changes:
- struct ieee80211_ht_cap is different enough that I preferred to keep
(and rename) it for now.
- mcs_rate in translate_scan was not read after being set, so I deleted
that part rather than using the renamed struct
- WLAN_CAPABILITY_BSS is replaced with WLAN_CAPABILITY_ESS which is the

These were obtained by doing a 'git diff | grep \/\*', in the previous diff

patch isn't great for catching these.
The result is:

/* Initialize IIO device */
/* Establish that the iio_dev is a child of the spi device */
/* Estabilish that the iio_dev is a child of the spi device */
/* Initiate the Industrial I/O device */

But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.

The change passes the parent device to the iio_device_alloc() call. This
also updates the devm_iio_device_alloc() call to consider the device object
as the parent device by default.
Having it passed like this, should ensure that any IIO device object
already has a device object as parent, allowing for neater control, like
passing the 'indio_dev' object for other stuff [like buffers/triggers/etc],
and potentially creating iiom_xxx(indio_dev) functions.
With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an
update to pass the parent object as a parameter.
In the next patch all devm_iio_device_alloc() calls will be handled.

Previously, the output format was programmed as part of the ioctl()
handler. However, this has two problems:
1) If there are multiple active streams with different output
formats, the hardware will use whichever format was set last
for both streams. Similarly, an ioctl() done in an inactive
context will wrongly affect other active contexts.
2) The registers are written while the device is not actively
streaming. To enable runtime PM tied to the streaming state,
all hardware access needs to be moved inside cedrus_device_run().
The call to cedrus_dst_format_set() is now placed just before the
codec-specific callback that programs the hardware.

After looking at the Intel Aero Yocto's version from:
https://download.01.org/aero/deb/pool/main/l/linux-4.4.76-aero-1.3/
It was noticed that this depends on an Android-specific modprobe parameter,
which uses a macro (INTEL_MID_BOARD) from this file:
arch/x86/include/asm/spid.h
>From the comments there, it looks like this macro parses a
variable passed at boot time:
cmdline : androidboot.spid=vend:cust:manu:plat:prod:hard

INTEL_BYT_TABLET_BLK_PRO = 0x0000
INTEL_BYT_TABLET_BLK_ENG = 0x8000
Well, this is something that we don't have upstream. So,
without further details about that, we can't really parse it.

in get operation and back in put. The overlay_start_x field value was not
copied from or to the user space struct.

XNR_BLENDING_SCALE_FACTOR is BIT(13), or 8192, which will easily fit
into a signed 32-bit integer. However, it is an unsigned long, which
means that negating it is the same as subtracting that value from
ULONG_MAX + 1, which causes it to be larger than a signed 32-bit
integer so it gets implicitly converted.
We can avoid this by using the variable isp_scale, which holds the value
of XNR_BLENDING_SCALE_FACTOR already, where the implicit conversion from
unsigned long to s32 already happened. If that were to ever overflow,
clang would warn: https://godbolt.org/z/EeSxLG
