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.
