I would just drop it.  It was not reported in five years so it's quite 
unlikely that people will see the bug.

I don't see anything in stable-kernel-rules.rst about how to mark such 
semantic conflicts, so no, it wasn't marked.  (The commit message does 
say "thanks to the previous patch", but I don't expect you or your 
scripts to notice that!).

Thanks,
