Found this while trying to make some changes to the kms_cursor_crc test. curs507a_acquire checks that the width and height of the cursor framebuffer are equal (asyw->image.{w,h}). This is actually wrong though, as we only want to be concerned that the actual width/height of the plane are the same. It's fine if we scan out from an fb that's slightly larger than the cursor plane (in fact, some igt tests actually do this).
How so? The scanout engine expects the data to be packed. Height can be larger, but width has to match.
