If anyone has any objections, please let me know. ------------------ From: Krzysztof Kozlowski commit 658342fd75b582cbb06544d513171c3d645faead upstream. Driver registered devm handler to cancel_work_sync() before even the work was initialized, thus leading to possible warning from kernel/workqueue.c on (!work->func) check, if the error path was hit before the initialization happened. Use devm_work_autocancel() on each work item independently, which handles the initialization and handler to cancel work.
