Description
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
