Guess it was inevitable I miss at least one.   This old beast must not
get coverage under any of the ppc defconfigs or allmodconfig, since I
did both...  are you using a custom config for an older box?

Anyway, the thing is controlled by a tristate, so this is the right fix.

I don't have _any_ other fixes queued for that cleanup series, so I'm fine
with this going via the ppc tree, since I'm sure there will be pending
commits there.

Thanks,
Paul.
