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 small fixes.  Mostly driver ones.  There is one core
  regression fix on a patch that was meant to fix some race issues on
  vb2, but that actually caused more harm than good.  So, we're just
  reverting it for now"
