From: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> All the manual update display code implements eventually ends up to just calls to omap_connector_flush(), currently implemented as an empty TODO stub. Remove it, the code can always be revived and implemented later if interest in manual update displays becomes a reality.
