Ok, that's great. I'm not saying that the current interface for this
driver is correct, that is why it is in the staging tree :)
It will change, don't worry.
But, what should it change into?

Simple to fix up.

That will be resolved as well.

Ok, that seems very reasonable. The whole module should probably have
that added as a prefix as well.

Lots :)

Care to send me patches to help resolve these issues to make it easier
for you?

Ah, good point, forgot that was already removed.
