Even if this all was ok, you are doing 3 things all in one change,
that's not allowed at all, you all know this.

Anyway, no new module parameters, this is not the 1990's, we have much
better ways to do this properly (hint, module parameters modify code,
you want to modify the options of a specific device.)
