The xbox dvd remote sends 24 bits, the first 12 bits are repeated
and inverted so only 12 bits are used. The upper 4 bits can be read
at offset 3. Ensure we pass this to rc-core and update the keymap
accordingly.

The Xbox DVD Movie Playback Kit is a USB dongle with an IR remote for the
Original Xbox.
Historically it has been supported by the out-of-tree lirc_xbox driver,
but this one has fallen out of favour and was just dropped from popular
Kodi (formerly XBMC) distributions.
This driver is heavily based on the ati_remote driver where all the
boilerplate was taken from - I was mostly just removing code.

This patch adds support to the CEC device implemented with a STM32
microcontroller in X86 SECO Boards, including UDOO X86.
The communication is achieved via Braswell integrated SMBus
(i2c-i801). The driver use direct access to the PCI addresses, due to
the limitations of the specific driver in presence of ACPI calls.
The basic functionalities are tested with success with cec-ctl and
cec-compliance.
Inspired by cros-ec-cec implementation, attaches to i915 driver

Some old Samsung drivers use the legacy crop API incorrectly:
the crop and compose targets are swapped. Normally VIDIOC_G_CROP
will return the CROP rectangle of a CAPTURE stream and the COMPOSE
rectangle of an OUTPUT stream.
The Samsung drivers do the opposite. Note that these drivers predate
the selection API.
If this 'QUIRK' flag is set, then the v4l2-ioctl core will swap
the CROP and COMPOSE targets as well.
That way backwards compatibility is ensured and we can convert the
Samsung drivers to the selection API.

Pull new experimental media request API from Mauro Carvalho Chehab:
"A new media request API
This API is needed to support device drivers that can dynamically
change their parameters for each new frame. The latest versions of
Google camera and codec HAL depends on such feature.
At this stage, it supports only stateless codecs.
It has been discussed for a long time (at least over the last 3-4
years), and we finally reached to something that seem to work.
This series contain both the API and core changes required to support
it and a new m2m decoder driver (cedrus).
As the current API is still experimental, the only real driver using
it (cedrus) was added at staging[1]. We intend to keep it there for a
while, in order to test the API. Only when we're sure that this API
works for other cases (like encoders), we'll move this driver out of
staging and set the API into a stone.
[1] We added support for the vivid virtual driver (used only for
testing) to it too, as it makes easier to test the API for the ones
that don't have the cedrus hardware"

If the wait for completion was interrupted, then make sure to cancel
any delayed work.
This can only happen if a transmit is waiting for a reply, and you press
Ctrl-C or reboot/poweroff or something like that which interrupts the
thread waiting for the reply and then proceeds to delete the CEC message.
Since the delayed work wasn't canceled, once it would trigger it referred
to stale data and resulted in a kernel oops.

Shifting the u8 value[3] by an int can lead to sign-extension
overflow. For example, if value[3] is 0xff and the shift is 24 then it
is promoted to int and then the top bit is sign-extended so that all
upper 32 bits are set. Fix this by casting value[3] to a u32 before
the shift.

In isif_probe(), there is a while loop to get the ISIF base address and
linearization table0 and table1 address. In the loop body, the function
platform_get_resource() is called to get the resource. If
platform_get_resource() returns NULL, the loop is terminated and the
execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the
first iteration because platform_get_resource() returns NULL and the
execution goes to 'fail_nobase_res'. Given that there is another while loop
at 'fail_nobase_res' and i equals to 0, one iteration of the second while
loop will be executed. However, the second while loop does not check the
return value of platform_get_resource(). This can cause a NULL pointer
dereference bug if the return value is a NULL pointer.
This patch avoids the above issue by adding a check in the second while
loop after the call to platform_get_resource().

Clang warns that the address of a pointer will always evaluated as true
in a boolean context.
drivers/media/pci/cx18/cx18-driver.c:1255:23: warning: address of
'cx->streams[i].video_dev' will always evaluate to 'true'
[-Wpointer-bool-conversion]
if (&cx->streams[i].video_dev)
~~ ~~~~~~~~~~~~~~~^~~~~~~~~
1 warning generated.
Check whether v4l2_dev is null, not the address, so that the statement
doesn't fire all the time. This check has been present since 2009,
introduced by commit 21a278b85d3c ("V4L/DVB (11619): cx18: Simplify the
work handler for outgoing mailbox commands")
