Issue is solved with a patch already on the way into mainline.
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=next-20230111&id=4444bc2116aecdcde87dce80373540adc8bd478b

Issue was found and fixed independently of the regression report, so no 
regression tags in the commit.
