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"

* 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:

  [media] media-device: fix infoleak in ioctl media_enum_entities()
  [media] fc2580: fix tuning failure on 32-bit arch
  [media] Prefer gspca_sonixb over sn9c102 for all devices
  [media] media: davinci: vpfe: make sure all the buffers unmapped and released
  [media] staging: media: davinci: vpfe: make sure all the buffers are released
  [media] media: davinci: vpbe_display: fix releasing of active buffers
  [media] media: davinci: vpif_display: fix releasing of active buffers
  [media] media: davinci: vpif_capture: fix releasing of active buffers
  [media] s5p-fimc: Fix YUV422P depth
  [media] s5c73m3: Add missing rename of v4l2_of_get_next_endpoint() function
  [media] rtl28xxu: silence error log about disabled rtl2832_sdr module
  [media] rtl28xxu: do not hard depend on staging SDR module
