Hi, I probably went a bit fast on the commit message. It seems to me that the Fixes line would be probably better with below one instead. Fixes: dd86dc2f9ae1 ("drm/sti: implement atomic_check for the planes") The same fix is actually necessary for all planes (cursor / gdp / hqvdp), which is related to the same original commit. Hence sti_cursor/sti_gdp and sti_hqvdp. Would you be ok to have those 3 fixes within a commit ?
