OK, makes sense.  I think you're on the right track, and if you extend
this patch to all of drivers/pci, I'll apply it.

I see you found the lines that checkpatch didn't complain about.
Maybe checkpatch doesn't look at things inside quoted strings?  That's
just a guess; I don't use checkpatch regularly.

If you plan to do other things, e.g., removing spaces between the
function name and open parenthesis, I'd like to have all the "white
space-only" changes in a single patch.
