Merge tag 'media/v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
"Media updates, including:
- Lots of improvements at the kABI documentation
- Split of Videobuf2 into a common part and a V4L2 specific one
- Split of the VB2 tracing events into a separate header file
- s5p-mfc got support for Exynos 5433
- v4l2 fixes for 64-bits alignment when running 32 bits userspace
on ARM
- Added support for SDR radio transmitter at core, vivid and hackrf
drivers
- Some y2038 fixups
- Some improvements at V4L2 colorspace support
- saa7164 converted to use the V4L2 core control framework
- several new boards additions, cleanups and fixups
PS: There are two patches for scripts/kernel-doc that are needed by
the documentation patches on Media. Jon is OK on merging those via
my tree"
