   4 Subject: [PATCH] staging: bcm2835-codec: Refactor default resolution
   5  code
   6
   7 The default resolution code was different for each role
   8 as compressed formats need to pass bytesperline as 0 and
   9 set up customised buffer sizes.
  10 This is common setup, therefore amend get_sizeimage and
  11 get_bytesperline to do the correct thing whether compressed
  12 or uncompressed.
