What changed from v1?

Always put that below the --- line, like the documentation says to do.

Also, why are you not cc:ing the maintainer of this driver?

And why change this function at all?  It can only return '4' (which is
crazy for other reasons...)  changeing the return value type makes no
sense to me, why did you make it?
