Otherwise fine and I can tidy that up whilst applying.
Yes, it's a typo. Please remove it while applying. Thanks!
Note that this is almost certainly too late for this cycle (we are about a week away from merge window subject to whatever Linus says for rc7 and new stuff needs some time to soak in next), but I'll plan to get it queued up early in the next one.
Noted. Thanks a lot!
