Sorry for the late reply I was sick.
The warning is, because the stable branch misses commit:
https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux.git/commit/?h=v5.18-next/soc&id=81c5a41d10b968ea89d5f44fe1e5c2fc70289209

So it's not a real issue and will go away once our branches land in upstream.
Is it OK for you to ignore the issue?

Matthias
