Another perhaps, there is a tag to indicate which patch introduce that bug, if you add this tag, the patch will be automatically backported into relevant stable kernel.

Width and height need to 64 bytes aligned when setting the format. Need to make sure all is 64 bytes align when use width and height to calculate buffer size.
