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 contains:
   - Exynos s5p-mfc driver got support for VP8 encoder
   - Some SoC drivers gained support for asynchronous registration
     (needed for DT)
   - The RC subsystem gained support for RC activity LED;
   - New drivers added: a video decoder(adv7842), a video encoder
     (adv7511), a new GSPCA driver (stk1135) and support for Renesas
     R-Car (vsp1)
   - the first SDR kernel driver: mirics msi3101.  Due to some troubles
     with the driver, and because the API is still under discussion, it
     will be merged at staging for 3.12.  Need to rework on it
   - usual new boards additions, fixes, cleanups and driver
     improvements"
