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"
