If platform_driver_register() fails, the function\nreturns the error directly and leaves the connector callback registered.\n\nThe later platform-device failure path already unregisters the callback.\nAdd the same cleanup before the final return when platform-driver\nregistration fails.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code.","state":0,"publishedAt":"2026-09-11T19:44:59.538+00:00","modifiedAt":"2026-10-19T08:49:29.665+00:00","affected":[{"ecosystem":"Vendor
