[PATCH 3/9] driver core: warn should device_move try to move a need_parent_lock device

[sashiko-bot at kernel.org]

> Currently, no device has need_parent_lock set and is moved by
> device_move. need_parent_lock is only set by the usb bus and very
> few device types ever use device_move.
> 
> Add a warning to device_move to catch should it ever be used on a
> device with need_parent_lock set. The combination would break
> the immutable relationship needed between parent and child for
> need_parent_lock when locking and unlocking both.
