You're often on the side of breaking patches in too small pieces :-) In this case the patch is small, so I don't think breaking it in two is required. It would be different if the changes were larger and more intertwined. > > > > > > unsigned int source_pad; > > > unsigned int sink_pad; -- Regards, Laurent Pinchart

When I was preparing this patch I also had this patch applied: https://patchwork.linuxtv.org/project/linux-media/patch/1595602732-25582-3-git-send-email-prabhakar.mahadev-lad.rj@bp.renesas.com/ And that caused the conflict with this YDS patch. However, I backed out the two renesas-vin-ycbcr-8b-g patches since there were a bunch comments for https://patchwork.linuxtv.org/project/linux-media/patch/1595602732-25582-2-git-send-email-prabhakar.mahadev-lad.rj@bp.renesas.com/ So after dropping those two patches this YDS patch now applies fine and will be included in the PR.
