However, that\nfunction does not wait until the work function finishes. This\nmeans that the callback function may still be running after\nthe driver's remove function has finished, which would result\nin a use-after-free.\n\nFix by calling cancel_delayed_work_sync(), which ensures that\nthe work is properly cancelled, no longer running, and unable\nto re-schedule itself."
