Flushing the worker\nduring unregister may therefore run a callback which queues the delayed\nwork after port_stop() has returned.\n\nThe delayed work can then run after devres has freed pmic_typec_port.\n\nUse disable_delayed_work_sync() in port_stop() to cancel a pending\ninstance and prevent the TCPM callbacks from queueing another one.\n\nThis issue was found by an in-house static analysis tool.","state":0,"publishedAt":"2026-09-16T10:33:29.7+00:00","modifiedAt":"2026-10-19T08:56:43.664+00:00","affected":[{"ecosystem":"Vendor
