The driver must not be hooked into any mips defconfigs or my build
coverage should have caught it (or it was merged after my change went on
in) -- in any case this is only the 2nd that slipped through out of
the big shuffle that came from that, so I think that is not bad.

Thanks for taking the cleanup approach here and not the one line
approach. Saves me doing the cleanup work myself later.
