Let me double check.

Just to rule out this possibility, linux-next was broken on Friday
(see https://lore.kernel.org/all/CAJuCfpFiEqRO4qkFZbUCmGZy-n_ucqgR5NeyvnwXqYh+RU4C6w@mail.gmail.com/).
I just checked and it's fixed now. Could you confirm that with the
latest linux-next you still see the issue?
