So here you are making reference to two amplifiers...

but here there's only one? I was expecting something like what we've
used for Maxim amplifiers with a codec configuration and dailink
components that list the two amplifiers.

static struct snd_soc_codec_conf max_98373_codec_conf[] = {
	{
		.dlc = COMP_CODEC_CONF(MAX_98373_DEV0_NAME),
		.name_prefix = "Right",
	},
	{
		.dlc = COMP_CODEC_CONF(MAX_98373_DEV1_NAME),
		.name_prefix = "Left",
	},
};

struct snd_soc_dai_link_component max_98373_components[] = {
	{  /* For Right */
		.name = MAX_98373_DEV0_NAME,
		.dai_name = MAX_98373_CODEC_DAI,
	},
	{  /* For Left */
		.name = MAX_98373_DEV1_NAME,
		.dai_name = MAX_98373_CODEC_DAI,
	},
};

Or is this a commit message problem and there's really only one amplifier?

The rest looks fine, I only have this one/two amplifier question.
