Sylwester Nawrocki 3c2ade017a [media] V4L: Drop bus_type check in v4l2-async match functions
These match_* functions are internal callbacks and are always
invoked only after checking asd->bus_type. So drop redundant
checks in match_i2c() and match_platform() functions.

We have reorganized the error handling into a simpler and more canonical

Additionally we removed extra empty lines, switched to devm_kzalloc(), and
substitute 'minor' by 'ret' in the igorplugusb_remote_probe() function.

Also found that the card does not have A0..A2 ISA pins connected, which means that the region size is 8 bytes.

Ezequiel Garcia b3ba8fa6b8 [media] media: stk1160: Ignore unchanged standard set
This commit adds an early check to vidioc_s_std() to detect if the
new and current standards are equal, and exit with success in that

This is needed to prevent userspace applications that might attempt
to re-set the same standard from failing if that's done when streaming
has started.

Alexey Khoroshilov ac22521cb2 [media] tlg2300: fix checking firmware in poseidon_probe()
check_firmware() makes sure firmware is in a device.
It returns zero on success and error code otherwise.
Also it sets down_firmware flag to 1 if downloading occurs.
The only caller poseidon_probe() checks down_firmware flag and
returns 0 without any initialization if it is set.
That looks very strange, so the patch removes down_firmware argument
of check_firmware() and returns error code if check_firmware() fails
in poseidon_probe().
Not tested on real hardware.

pointer on commands. With the new firmware, there is only a single set of
read/write pointers which need to be restored between context switches.
This allows more than four active contexts at the same time.
All auxiliary buffers are now allocated through a helper function to avoid

Philipp Zabel 33bdd5a88a [media] mem2mem: add support for hardware buffered queue
On mem2mem decoders with a hardware bitstream ringbuffer, to drain the
buffer at the end of the stream, remaining frames might need to be decoded
from the bitstream buffer without additional input buffers being provided.
To achieve this, allow a queue to be marked as buffered by the driver, and
allow scheduling of device_runs when buffered ready queues are empty.
This also allows a driver to copy input buffers into their bitstream
ringbuffer and immediately mark them as done to be dequeued.
The motivation for this patch is hardware assisted h.264 reordering support
in the coda driver. For high profile streams, the coda can hold back
out-of-order frames, causing a few mem2mem device runs in the beginning, that
don't produce any decompressed buffer at the v4l2 capture side. At the same
time, the last few frames can be decoded from the bitstream with mem2mem device
runs that don't need a new input buffer at the v4l2 output side. The decoder
command ioctl can be used to put the decoder into the ringbuffer draining
end-of-stream mode.

Pull ACPI video support fixes from Rafael Wysocki:
 "I'm sending a separate pull request for this as it may be somewhat
  controversial.  The breakage addressed here is not really new and the
  fixes may not satisfy all users of the affected systems, but we've had
  so much back and forth dance in this area over the last several weeks
  that I think it's time to actually make some progress.

  The source of the problem is that about a year ago we started to tell
  BIOSes that we're compatible with Windows 8, which we really need to
  do, because some systems shipping with Windows 8 are tested with it
  and nothing else, so if we tell their BIOSes that we aren't compatible
  with Windows 8, we expose our users to untested BIOS/AML code paths.

  However, as it turns out, some Windows 8-specific AML code paths are
  not tested either, because Windows 8 actually doesn't use the ACPI
  methods containing them, so if we declare Windows 8 compatibility and
  attempt to use those ACPI methods, things break.  That occurs mostly
  in the backlight support area where in particular the _BCM and _BQC
  methods are plain unusable on some systems if the OS declares Windows
  8 compatibility.

  [ The additional twist is that they actually become usable if the OS
    says it is not compatible with Windows 8, but that may cause
    problems to show up elsewhere ]

  Investigation carried out by Matthew Garrett indicates that what
  Windows 8 does about backlight is to leave backlight control up to
  individual graphics drivers.  At least there's evidence that it does
  that if the Intel graphics driver is used, so we've decided to follow
  Windows 8 in that respect and allow i915 to control backlight (Daniel
  likes that part).

  The first commit from Aaron Lu makes ACPICA export the variable from
  which we can infer whether or not the BIOS believes that we are
  compatible with Windows 8.

  The second commit from Matthew Garrett prepares the ACPI video driver
  by making it initialize the ACPI backlight even if it is not going to
  be used afterward (that is needed for backlight control to work on
  Thinkpads).

  The third commit implements the actual workaround making i915 take
  over backlight control if the firmware thinks it's dealing with
  Windows 8 and is based on the work of multiple developers, including
  Matthew Garrett, Chun-Yi Lee, Seth Forshee, and Aaron Lu.

  The final commit from Aaron Lu makes us follow Windows 8 by informing
  the firmware through the _DOS method that it should not carry out
  automatic brightness changes, so that brightness can be controlled by
  GUI.

  Hopefully, this approach will allow us to avoid using blacklists of
  systems that should not declare Windows 8 compatibility just to avoid
  backlight control problems in the future.

     used by driver code to determine whether or not the BIOS believes
     that we are compatible with Windows 8.
