   4 Subject: [PATCH] staging/bcm2835-codec: Implement additional
   5  g_selection calls for decode
   6
   7 v4l_cropcap calls our vidioc_g_pixelaspect function to get the pixel
   8 aspect ratio, but also calls g_selection for V4L2_SEL_TGT_CROP_BOUNDS
   9 and V4L2_SEL_TGT_CROP_DEFAULT. Whilst it allows for vidioc_g_pixelaspect
  10 not to be implemented, it doesn't allow for either of the other two.
  11
  12 Add in support for the additional selection targets.
