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:
 "This series contain:
   - new i2c video drivers: ml86v7667 (video decoder),
                            ths8200 (video encoder)
   - a new video driver for EasyCap cards based on Fushicai USBTV007
   - Improved support for OF and embedded systems, with V4L2 async
     initialization and a better support for clocks
   - API cleanups on the ioctls used by the v4l2 debug tool
   - Lots of cleanups
   - As usual, several driver improvements and new cards additions
   - Revert two changesets that change the minimal symbol rate for
     stv0399, as request by Manu
   - Update MAINTAINERS and other files to point to my new e-mail"
