If anyone has any objections, please let me know. ------------------ From: Hongyan Xu [ Upstream commit 60c5b8a9ef4dbc5d69bbc1a960fe55826cb3b643 ] The USB notifier and initial VBUS detection can schedule isp->work. The remove path unregisters the notifier and power supply, but does not wait for queued or running work before tearing down the power supply state. Cancel the work after unregistering the notifier. Do this before unregistering the power supply. This issue was found by a static analysis tool.
