What you are trying to do here is to put GPIO maintainers / heavy
contributors on a minefield (basically moving your job to their
shoulders). Please, provide a proper namespace and not gpio_ one. I'm
talking in my "GPIO heavy contributor" hat on.

With that fixed I can survive w/o pr_fmt() being in this patch. If you
are going to address this, you may add my tag in a new version.
