Again, I'll hold off on sending v5 for now and (if no > other problems) happy if this gets done when applied. > > > > Reviewed-by: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> I didn't want to churn the whole series, so I ended up posting a patch that addressed the issues you mentioned and a few others. It could be squashed into this patch if desired. I'm also happy to re-post this series with that patch squashed in.
