Hi Roy,

You're welcome. Please note that I just scan for, well, common build
issues. Ie, stuff that requires no domain specific knowledge.

Good timing. I was pondering how to handle 04/11, a big patch that
exports 79 (!) symbols. Many of those appear to have no users.

At the end of the day, what matters is what the people that need to sign
off on these drivers (ppc? netdev?) are comfortable with. I know that
some maintainers won't even bother looking at code that has no callers.

In the mean time I'll skip the exports for the remainder of this series.

Thanks,
