Thanks. For testing that one you'd have to revert the other first, I
think, you could also just test this one:

https://patchwork.kernel.org/project/linux-wireless/patch/20260519235713.49109-2-lucid_duck@xxxxxxxxxxxxx/

But I think they're basically all equivalent.

Since we eventually need a patch to apply w/o reverting, Devin's is
probably better than my old one.
