Thanks for the patch - it looks to be the correct solution.

If being a stickler then it should call drm_panel_disable so that the framework gets notified of everything too, but as this is in an unload path it doesn't really matter.

I have no intention of upstreaming this driver, so I'm really not worried over the checkpatch warning for no commit description.
