This is not going to be practical.  If the previous patch is accepted,
then this it not needed.  If the previous patch is not yet accepted, then
there needs to be a vn+1 putting the patches together into a series.

In the realm of small cleanups to this driver, the extra space in front of
the - above is a bit annoying.
