If driver_register() fails, those requests remain in the global\nIDR and retain pointers to the module's ID table. Once the failed module\nload releases that storage, later request matching or SCMI device creation\ncan dereference the stale pointers.\n\nUnrequest the complete protocol table before returning the registration\nfailure.
