Ungh, that's embarrassing; I really should have caught that in review. Sigh. At least it shouldn't cause anything to blow up, just a less than helpful message.
I pulled the original patch from linux-audit#next just now, I'll re-add it once we sort this out.

Granted 32 bytes should be big enough for the string, but I would feel better if we used snprintf() here; make the change and I'll merge the patch with the original and push it back to linux-audit#next.
Normally I'm not a big fan of amending patches after they have been committed, but in this case it is in the next branch (doing this for upstream or stable-X is a big "no") and nothing sits on top of it.
