In the Linux kernel, the following vulnerability has been resolved: Input:
appletouch - initialize work before device registration Syzbot has reported
warning in __flush_work(). This warning is caused by work->func == NULL,
which means missing work initialization. This may happen, since
input_dev->close() calls cancel_work_sync(&dev->work), but dev->work
initalization happens after input_register_device() call. So this patch
moves dev->work initialization before registering input device
