My bot found errors running 'make dt_binding_check' on your patch:

Error: Documentation/devicetree/bindings/clock/qcom,audiocc-sm8250.example.dts:25.30-31 syntax error
FATAL ERROR: Unable to parse input tree

See https://patchwork.ozlabs.org/patch/1366127

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

Is this check done against linux-next?

or linux master?

I have rechecked this once again on next and I see no check failures.
Next has a patch [1] which adds defines in header file that are used in 
example! Possibly that is what is making the check fail!


thanks,
srini
