Strange.  I was quite sure at the time that I had removed all traces of
USB_SUSPEND, but clearly that was wrong.

Anyway, I'll send in a patch to remove the remaining usages.  Many of
them are in comments, but some are in Kconfig files where they will
really matter.

Or they survived in some other manner.  It's possible that I edited
these files but then failed to include them in the final patch.

What other things seemed odd about Greg's pull request?
