I'm not convinced by those arguments, but ultimately it's between you
and the maintainers. If you're going with the ASCII route, then I have
another review comment. Currently in your patch, if kstrtoint fails,
you print, but then break out of the loop and try to write the
partially parsed descriptor anyway. That "break" should probably be
changed to a "goto out".
