Hm, that's weird. Of course I did the dt_binding_check before submission, but
even after the dt-schema repo update I failed to see the error:

$ make -j8 ARCH=mips CROSS_COMPILE=mipsel-baikal-linux- dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/usb/usb-hcd.yaml
  CHKDT   Documentation/devicetree/bindings/usb/usb-hcd.yaml
  SCHEMA  Documentation/devicetree/bindings/processed-schema-examples.yaml
  DTC     Documentation/devicetree/bindings/usb/usb-hcd.example.dt.yaml
  CHECK   Documentation/devicetree/bindings/usb/usb-hcd.example.dt.yaml

Rob, any idea why has the bot got mad at me?
