From 42b1168b921a0183da6754f43192f7090145feed Mon Sep 17 00:00:00 2001

Subject: [PATCH 483/725] 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.
