I'll grant you that the current implementation of drm_panel_detach() is not very useful, but then you add code to drm_panel_detach() in the next patch and mention in the commit message that panel drivers should be calling the drm_panel_detach() function to remove the link. This is confusing. Can you clarify? Thierry
