Before this patch the resulting values from a try_fmt were different then those from a s_fmt with the same parameters. try_fmt simply did not touch / fill some values like bytesperline at all. This patch also corrects bytesperline to the proper value for a planar format such as the YUV420P format the pwc driver produces, which is the bytesperline value for the biggest plane, rather then those of all planes added together.
