Clean up all of the kernel-doc issues in drm_connector.c:
drivers/gpu/drm/drm_connector.c:2611: warning: Excess function parameter 'connector' description in 'drm_connector_oob_hotplug_event' drivers/gpu/drm/drm_connector.c:2611: warning: Function parameter or member 'connector_fwnode' not described in 'drm_connector_oob_hotplug_event'

drm_connector.c:2315: warning: missing initial short description on line: * drm_connector_set_panel_orientation_with_quirk -
[The last warning listed is probably a quirk/bug in scripts/kernel-doc.]
