We have github actions that we run when a new patch appears on patchwork e.g:

https://patchwork.kernel.org/project/bluetooth/patch/20230124174714.2775680-3-neeraj.sanjaykale@xxxxxxx/

For now I'd keep it simple since otherwise we would have to probably
attempt to apply and make with DT_CHECKER_FLAGS every patch, well
perhaps that is ok if that doesn't produce too many false positives,
otherwise we have to filter the output like we do with the likes of
smatch and building with make W=1 C=1.
