Woah, you just prevented this driver from ever being able to be
unloaded.

That's not a "cleanup" that's a major change in how things work.  I'm
sure, if you want to continue down this line, there are more things you
can remove from the code, right?

What is the real issue here?  What happens if you unload the bus?  What
goes wrong?  Can it be fixed?

This is a pretty big commitment...

thanks,
