Some userspace presumes that the first connected connector is the main display, where it's supposed to display e.g. the login screen. 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.
