Yes, I understand that it's not serious. I'm arguing instead that it's still
wrong. If you ship a kernel with support for two dozen different controllers,
you certainly wouldn't want to list them all as present devices and
have to go through loading each driver at boot time, just to find that
they are not actually present.
