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

Browse Source 
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"
