This looks like still not being applied and now it is a warning in Linus' tree.
Can this be applied and sent as fixes?

There's still one warning remaining after applying this series which I reported:
scripts/Makefile.dtbs:20: .dtbo is not applied to any base:
mt8395-radxa-nio-12l-8-hd-panel.dtbo
It's fixed in my original patch. Can you all take that and drop the bpi hunks.

afair the series was sent after the pull-request from angelo and maybe he waited for an ack from you/rob before applying ;)
if it helps i collected the commits for (possibly) sending as fix

My bot found new DTB warnings on the .dts files added or changed in this series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date:
pip3 install dtschema --upgrade
This patch series was applied (using b4) to base:
Base: attempting to guess base-commit...

Base: tags/next-20251119 (use --merge-base to override)
If this is not the correct base, please add 'base-commit' tag (or use b4 which does this automatically)
