The reset devm action only unregisters\nthe notifier and was registered before the power supplies, so devm frees\nbq->charger on unwind before the action runs; a usb_work still queued can\nthen dereference it.\n\nRegister the reset action after the power supplies, so it unregisters\nthe notifiers and drains usb_work before the supplies are released.\nInitialize usb_work and obtain the PHY references before registering\nthe notifiers, so the worker cannot run before the supplies exist.\n\nFound by static analysis.","state":0,"publishedAt":"2026-09-11T19:43:31.882+00:00","modifiedAt":"2026-10-19T08:47:23.191+00:00","affected":[{"ecosystem":"Vendor
