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

Documentation/devicetree/bindings/media/i2c/chrontel,ch7322.yaml: $id: relative path/filename doesn't match actual path or filename
	expected: http://devicetree.org/schemas/media/i2c/chrontel,ch7322.yaml#

See https://patchwork.ozlabs.org/patch/1290799

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
