Not off hand.

When I run builds on patches I author, I run them twice concurrently.
Once on the commit I'm basing on and once on the HEAD of my patchset.  I
then diff the two.  So as long as the number of errors and warnings stay
the same or reduce, we're golden.

Perhaps the same method could be used with `kernel-doc`?
