hmpf. Which tool emitted that warning? sparse?

It is somewhat unconventional coding style and it'd be good if
checkpatch were to warn so that we don't _add_ such things to the tree.

But IMO it's such a minor thing that once it _is_ in the tree, it's not
really worth the patch noise to go and fix it up.
