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:
"Most of the changes are drivers fixes (rtl28xuu, fc2580, ov7670,
davinci, gspca, s5p-fimc and s5c73m3).

There is also a compat32 fix and one infoleak fixup at the media
controller"
