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 at ravnborg.org>
If I get time this weekend I will rebase/test and send the
set of patches out.
