Input: serio - take drv_mutex in serio_cleanup()
We need to take serio->drv_mutex in serio_cleanup() to prevent the function from being called while driver is in the middle of attaching to a serio port. Such situation can happen with i8042 and atkbd drivers if user rapidly presses Ctrl-Alt-Del during system startup, and leads to kernel oops.
