This leads to a WARN()[1]. The orientation property is known earlier. For example, some panels parse the property through device tree during probe. The series add a panel API drm_connector_set_orientation_from_panel() for drm/kms drivers. The drivers can call the API to set panel's orientation before drm_dev_register(). Panel needs to implement .get_orientation callback to return the property.
