A different dependency should be noted in *this* patch. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

I have updated MAINTAINERS as part of 4/6 patch, and there is no mention of Documentation/devicetree/bindings/virtio/ in MAINTAINERS post 4/6 patch. I have ran the tool locally as well on top of 4/6 and then 5/6 but it never reported this error. Anyway as per your latest comment I should be moving VMBus to bus folder instead, so no need to worry about this. Regards, Saurabh > > Rob
