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:

 - Missing MAINTAINERS entries were added for several drivers

 - Adds V4L2 support for DMABUF handling, allowing zero-copy buffer
   sharing between V4L2 devices and GPU

 - Got rid of all warnings when compiling with W=1 on x86

 - Add a new driver for Exynos hardware (s3c-camif)

 - Several bug fixes, cleanups and driver improvements
