NAME
     DEVICE_DETACH — detach a device


SYNOPSIS
     #include <sys/param.h>
     #include <sys/bus.h>

     int
     DEVICE_DETACH(device_t dev);


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.
