For laptops, this should be the main panel. This patch call drm_helper_move_panel_connectors_to_head() after drm_bridge_connector_init() to make sure eDP stay at head of connected connector list. This fixes unexpected corruption happen at eDP panel if eDP is not placed at head of connected connector list.
