I'm not quite happy with that patch. Specifically, I see a risk of
module_put being called too often.

Could you explain in some more detail what bug you are trying to fix?
Do you have a sequence of events which leads to a situation where the
bas_gigaset module cannot be unloaded but should be?

Thanks,
Tilman
