+Subject: [PATCH] staging: bcm2835-codec: Correct port width calc for
+ truncation
+
+The calculation converting from V4L2 bytesperline to MMAL
+width had an operator ordering issue that lead to Bayer raw 10
+(and 12 and 14) setting an incorrect stride for the buffer.
+Correct this operation ordering issue.
