Thanks, I sent the same change three weeks ago at this point:
https://lore.kernel.org/20231120-fix-at91-modpost-warnings-v1-1-813671933863@kernel.org/
Your commit message is a little better than mine and I don't really care which one goes in but it would be good if this could get cleared up soon...
