DEVICE_UNREGISTER(9)              Device drivers infrastructure              DEVICE_UNREGISTER(9)



NAME
       device_unregister - unregister device from system.

SYNOPSIS
       void device_unregister(struct device * dev);

ARGUMENTS
       dev
           device going away.

DESCRIPTION
       We do this in two parts, like we do device_register. First, we remove it from all the
       subsystems with device_del, then we decrement the reference count via put_device. If that
       is the final reference count, the device will be cleaned up via device_release above.
       Otherwise, the structure will stick around until the final reference to the device is
       dropped.
