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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
./Documentation/devicetree/bindings/iio/light/amstaos,tsl2591.yaml: $id: relative path/filename doesn't match actual path or filename
	expected: http://devicetree.org/schemas/iio/light/amstaos,tsl2591.yaml#

See https://patchwork.ozlabs.org/patch/1440199

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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.
