Currently the master drm driver is not protected against the attached. The device_link with DL_FLAG_AUTOREMOVE should make sure the drm device is unbound before the panel driver becomes unavailable. The device_link is removed when drm_panel_detach() is called. The drm_panel_detach() should be called by the panel driver it self when it is removed. Otherwise the both driver are racing to delete the same link.
