Report on our issue tracker with discussion:
https://github.com/ClangBuiltLinux/linux/issues/1551
Ard has a fix that should resolve this here:
https://lore.kernel.org/r/20211222104939.1154570-1-ardb@kernel.org/
I am about to reply with a Tested-by tag, I have tested LLVM 12 and 13
and my 14 build is running right now. Might be helpful for you to run
that patch through your matrix as well.
Cheers,
Nathan
