Pull media fixes from Mauro Carvalho Chehab:
 "For some last time fixes:
   - a regression detected on Kernel 3.16 related to VBI Teletext
     application breakage on drivers using videobuf2 (see
     https://bugzilla.kernel.org/show_bug.cgi?id=84401).  The bug was
     noticed on saa7134 (migrated to VB2 on 3.16), but also affects
     em28xx (migrated on 3.9 to VB2);
   - two additional sanity checks at videobuf2;
   - two fixups to restore proper VBI support at the em28xx driver;
   - two Kernel oops fixups (at cx24123 and cx2341x drivers);
   - a bug at adv7604 where an if was doing just the opposite as it
     would be expected;
   - some documentation fixups to match the behavior defined at the
     Kernel"
