Two (2) patches have been posted for this build error (in chronological order):

2022-10-29:
  https://lore.kernel.org/lkml/20221030055636.3139-1-rdunlap@infradead.org/
2022-12-15:
  https://lore.kernel.org/all/20221215170036.2308972-1-arnd@kernel.org/

Can someone apply one of them or at least comment on them?
Philipp?
