Same question as before, is this a regression, and if so, any pointers to a fix?
thanks,

This is a known warning on Linus's tree. The fix should come from Linus's tree.

Great, please report the issue there, as there's nothing I can do about it in the 5.15.y tree until it is resolved there as you know.
