If anyone has any objections, please let me know. ------------------ From: Hongyan Xu [ Upstream commit dfc859bb8d332c525872f1a44028137724fa1998 ] The USB notifier and initial charger detection can schedule info->work. The remove path unregisters the notifier, but does not cancel queued or running work before the devm-allocated driver data is released. Set the platform drvdata used by remove, then cancel the work after unregistering the notifier. This issue was found by a static analysis tool.
