Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - Some cleanups at V4L2 documentation

 - new drivers: ts2020 frontend, ov9650 sensor, s5c73m3 sensor,
   sh-mobile veu mem2mem driver, radio-ma901, davinci_vpfe staging
   driver

 - Lots of missing MAINTAINERS entries added

 - several em28xx driver improvements, including its conversion to
   videobuf2

 - several fixups on drivers to make them to better comply with the API

 - DVB core: add support for DVBv5 stats, allowing the implementation of
   statistics for new standards like ISDB

 - mb86a20s: add statistics to the driver

 - lots of new board additions, cleanups, and driver improvements.
