The extcon IRQ schedules a work item. IRQ is requested using devm while WQ is cancelld at remove(). This mixing of devm and manual unwinding has potential case where the WQ has been emptied (.remove() was ran) but devm unwinding of IRQ was not yet done. It may be possible the IRQ is triggered at this point scheduling new work item to the already flushed queue. According to the input documentation the input device allocated by devm_input_allocate_device() does not need to be explicitly unregistered. Use the new devm_work_autocancel() and remove the remove() to simplify the code.
