Just spotted this while doing a drive-by refactoring, this doesn't really
work. The THIS_MODULE must be in the source code for your driver, and
can't be in some helper library module like tinydrm.ko.

Yeah, you're right.

I'm working on a macro to make this easier, and I guess you could try to
integrate that into your driver macro somehow (probably simplest to
generate the entire structure and just pass name+desc to that macro,
everything else is boilerplate anyway).

I'll cc you on that patch.

Thanks.

Noralf.
