For uncompressed formats in capture devices, the v4l2_buffer::bytesused field should have the same value as the v4l2_pix_format::sizeimage field reported by the VIDIOC_G_FMT ioctl. Print a warning on VIDIOC_DQBUG when the values don't match. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
