called when fep->bufdesc_ex is available.\nHowever, fec_probe() unconditionally calls fec_ptp_stop() on the\nfailed_init path, and fec_drv_remove() unconditionally calls\nfec_ptp_stop() during device removal.\n\nCheck fep->bufdesc_ex before calling fec_ptp_stop() in both paths\nto avoid stopping PTP when it was not initialized.","state":0,"publishedAt":"2026-09-17T16:05:41.003+00:00","modifiedAt":"2026-10-19T08:57:13.609+00:00","affected":[{"ecosystem":"Vendor
