Thanks.  Do you know if there's an easy way to find these ahead of time?
I usually run './scripts/kernel-doc -v -none ${filename}' to catch
kerneldoc issues.  I did run it on include/crypto/sha3.h, but for some
reason it doesn't detect this issue.

'make htmldocs' doesn't find it either, but does generate a bunch of
unrelated warnings.  I may be missing an option to make it even more
verbose.  Either way, it's also slow to run.
