Thierry, Sam, any opinion? Agreed, I have following patch in my panel patch queue: drm/drm_panel: no error when no callback The callbacks in drm_panel_funcs are optional, so do not return an error just because no callback is assigned. Signed-off-by: Sam Ravnborg <sam@xxxxxxxxxxxx> If I get time this weekend I will rebase/test and send the set of patches out.
