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.
