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.
