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"

Useful to handle the wrapping of a + * circular buffer. + * @buffer2_len: Length of the filtered section data in @buffer2, + * including headers and CRC. + * @source: Indicates which section feed is the source of the + * callback. + * + * This function callback prototype, provided by the client of the demux API, + * is called from the demux code. The function is only called when + * filtering of sections has been enabled using the function + * &dmx_ts_feed.@start_filtering. When the demux driver has received a + * complete section that matches at least one section filter, the client + * is notified via this callback function. Normally this function is called + * for each received section; however, it is also possible to deliver + * multiple sections with one callback, for example when the system load + * is high. If an error occurs while receiving a section, this + * function should be called with the corresponding error type set in the + * success field, whether or not there is data to deliver. The Section Feed + * implementation should maintain a circular buffer for received sections. + * However, this is not necessary if the Section Feed API is implemented as + * a client of the TS Feed API, because the TS Feed implementation then + * buffers the received data. The size of the circular buffer can be + * configured using the &dmx_ts_feed.@set function in the Section Feed API. + * If there is no room in the circular buffer when a new section is received, + * the section must be discarded.
