Devres runs in reverse order, so the IRQ is freed\nbefore cancel_work_sync(), including when probe fails.  A cancel left in\n.remove() cannot get that order.  Initializing the work first also stops\na pending watchdog interrupt from queuing an uninitialized work item.\nProbe currently calls INIT_WORK() only after devm_request_irq().\n\nThis issue was identified during our ongoing static-analysis research\nwhile reviewing kernel code."
