If you create a device with a call to device_create() with a dev_t set,
it is usually cleaned up with a call to device_destroy(), but you are
right, a simple call to device_unregister() will still work properly.
So nevermind, sorry for the noise.
What you do need to determine is if this is a device node you really
want to be creating in this manner, as it is a new user/kernel API,
right?
