 *   drm_object_attach_property() before the object is visible to userspace.
 *
 * - For objects with dynamic lifetimes (as indicated by a non-NULL @free_cb) it
 *   provides reference counting through drm_mode_object_get() and
 *   drm_mode_object_put(). This is used by &drm_framebuffer, &drm_connector
