Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media fixes from Mauro Carvalho Chehab:
"A series of bug fix patches for v3.15-rc1. Most are just driver
fixes. There are some changes at remote controller core level, fixing
some definitions on a new API added for Kernel v3.15.
It also adds the missing include at include/uapi/linux/v4l2-common.h,
to allow its compilation on userspace, as pointed by you"
