Ok, I didn't see Greg's email about dynamic debugging. I guess you
shouldn't refresh the second patch. I'm not sure how I would go about
converting the xHCI driver to dynamic debugging, as I haven't looked
into it. Is there any documentation/simple examples?

Greg, does the less-verbose patch with log levels still make sense if
the driver got converted over to dynamic debugging?
