There is https://llvm.org/docs/HowToReleaseLLVM.html#release-patch-rules, but it's not very useful :)

I don't think there is much value in backporting theoretical miscompilation fixes to the release branch, but I don't particularly care in this case, as the patch itself is simple and unlikely to significantly affect anything.
