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:
 "Media fixes for:
   - one Kconfig fix patch;
   - one patch fixing DocBook breakage due to the drivers/media UAPI
     changes;
   - the remaining UAPI media changes (DVB API).

  I'm aware that is is a little late for the UAPI renames for the DVB
  API, but IMHO, it is better to merge it for 3.7, due to two reasons:

   1) There is a major rename at 3.7 (not only uapi changes, but also
      the entire media drivers were reorganized on 3.7, in order to
      simplify the Kconfig logic, and easy drivers selection, especially
      for hybrid devices).  By confining all those renames there at 3.7
      it will cause all the harm at for media developers on just one
      shot.  Stable backports upstream and at distros will likely
      welcome it as well, as they won't need to check what changed on
      3.7 and what was postponed for on 3.8.

   2) The V4L2 DocBook Makefile creates a cross-reference between the
      media API headers and the specs.  This helps us _a_lot_ to be sure
      that all API improvements are properly documented.  Every time a
      header changes from one place to another, DocBook/media/Makefile
      needs to be patched.  Currently, the DocBook breakage patch
      depends on the DVB UAPI."
