DEVICE_DETACH

DESCRIPTION¶
Detach a device. This can be called if the user is replacing the driver software
or if a device is about to be physically removed from the system (e.g. for
pccard(4) devices).
The method should deallocate any system resources allocated during the
DEVICE_ATTACH(9) method and reset the hardware to
a sane state (i.e., disable interrupts etc.)
RETURN VALUES¶
Zero is returned on success, otherwise an appropriate error is returned.
