Great, can you add a Fixes: tag when you resend these? > But similar changes like: > 742203cd "drm: rockchip: add missing registers for RK3066" > 8d544233 "drm/rockchip: vop: Add directly output rgb feature for px30" > did not have any "Fixes" reference. Just because people didn't properly tag things in the past, doesn't mean you should perpetuate that problem :) thanks, greg k-h _______________________________________________ Linux-rockchip mailing list Linux-rockchip@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-rockchip
