It would be readable if
Required properties:
- compatible		: "fsl,imx-audio-es8328"
- model			: The user-visible name of this sound complex
- ssi-controller	: The phandle of the i.MX SSI controller
- jack-gpio		: Optional GPIO for headphone jack
...

should match open parenthesis:
	dev_err(dev, "mux-int-port: hardware only has %d mux ports\n",
		MUX_PORT_MAX);

Dto..

This field updated by module_platform_driver()... No need to do manually..
