--- Comment #12 from Nicolas Dufresne (stormer) <nicolas at ndufresne.ca> ---
Well, this guy didn't understood the bug. If it was vertical padding issue, the
U and the V planes would be 16 pixels off, and you would notice the colors
being slightly wrong. In this case it's just the bytesused does not match size
image. It could be legitimate in userptr or dmabuf-import mode, but that, I
don't know. Other then that, V4L has mplane format that cover all this. With
these formats, each plane is specified separately. This gives full control over
padding between planes, even allow having separate allocation per plane.

Other then that, I think this patch can land. If something worked before and
it's not dangerous to workaround, then let's go.
