So it's a candidate to ignore, right?

That's what I was getting at... should we ignore it in checkpatch and
simply review any new volatile variables?  Or should we not ignore it
in checkpatch and have exceptions to "no errors, no warnings"?

I also think that for code cleanup where progress can be incremental,
the rules may need to be a little more lenient.
