Yes, Nathan was alert, and saved me too from bisecting failure to boot linux-next in another thread.
And I see from https://lore.kernel.org/lkml/c85a77a3-409b-3e83-08a7-ac7e1888790d@samsung.com/ that Marek also found it: and tried to fix it, but found it goes too wide.
I made a patch of the offending series with git diff 78ffa3e58d93^ 2b109cffe683 and then reverted that cleanly from next-20220923: works for me.
