Old? Your change came for v6.8 and this was sent when all trees were
based on v6.7-rc1. What newer tree could have this been?

That's a timing issue. For that particular case, where this was
targeting next-next cycle, you should have based this on linux-next. In
other cases this would require cross-tree merging due to dependencies
which none of us were aware, so no harm.
