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:

 - dvb core: there is a regression found when used with xine.  For
   whatever unknown reason, xine (and xine-lib clients) wants that the
   frontend to tell what frequency he is using even before the PLL lock
   (or at least, it expects a non-zero frequency).

   On DVB, the frequency is only actually known after a frequency
   zig-zag seek, done by the DVB core.  Anyway, the fix was trivial.
   That solves Fedora BZ#808871.

 - ivtv: fix a regression when selecting the language channel

 - uvc: fix a race-related crash

 - it913x: fixes firmware loading

 - two trivial patches (a dependency issue at a radio driver at sound
   Kconfig, and a warning fix on dvb).
