From 263f7d61a4201cde16849b2d016251806e7418be Mon Sep 17 00:00:00 2001 From: Fan Wu Date: Thu, 20 Aug 2026 13:53:06 +0000 Subject: usb: typec: qcom-pmic-typec: disable cc_debounce_dwork on stop cc_debounce_dwork is queued from the set_cc() and start_toggling() callbacks, which run from TCPM's kthread worker. port_stop() returns before tcpm_unregister_port() destroys that worker. Flushing the worker during unregister may therefore run a callback which queues the delayed work after port_stop() has returned. The delayed work can then run after devres has freed pmic_typec_port. Use disable_delayed_work_sync() in port_stop() to cancel a pending instance and prevent the TCPM callbacks from queueing another one. This issue was found by an in-house static analysis tool.
