Hi Dmitry, my linux-next builds for Fedora failed today with this error:

A quick search on lore found that the 0-day bot encountered a similar
problem early July:
https://lore.kernel.org/all/[email protected]/
Back then it afaics was caused by "cpufreq: qcom-nvmem: create L2 cache
device" which is new in todays next, which makes it a likely suspect for
my problem. That's why I decided to write this mail. But note, I didn't
verify if that patch really causes the trouble; hence if you think it
might be something entirely different, let me know.
Full build log:
https://copr-be.cloud.fedoraproject.org/results/@kernel-vanilla/next/fedora-38-aarch64/06516038-next-next-all/builder-live.log.gz
I don't have the config file at hand, but it should be the following one
processed with "make olddefconfig"

Ciao, Thorsten

of_find_next_cache_node() needs to be exported for modules.
Dmitry, can you send a patch for that and mention that it needs to go
in via my tree ?
