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