I think I was just getting overwhelmed with the sea of error logs I
saw (for unrelated files). If I don't use the flags it's way too noisy
and it's not always the first thing that's reported.

This is what I see now and I think I now understand what to look for.

No, I always develop on Linus's tree and test it on an android kernel
that's behind Linus's tree by a month or so.

My yamllint version is 1.32.0, but until 2 weeks ago the latest
yamllint version was 1.33.0.

And dt-schema is  2022.08.2-5 and I had to revert this from Linus's
tree to get it to work:
b32dcf23a03e dt-bindings: Drop kernel copy of common reserved-memory bindings

Unfortunately, AFAIK, I don't have permissions to change the package
repo, so can't really install a newer version.

Thanks for the tips.
