I don't quite follow the initialization part. In the 4-ch case, you will
setup control and widgets but...

... in the 2 ch case you use this function
int max_98373_spk_codec_init(struct snd_soc_pcm_runtime *rtd)
{
struct snd_soc_card *card = rtd->card;
int ret;
ret = snd_soc_dapm_add_routes(&card->dapm, max_98373_dapm_routes,
ARRAY_SIZE(max_98373_dapm_routes));
if (ret)
dev_err(rtd->dev, "Speaker map addition failed: %d\n", ret);
return ret;
}
which only adds routes. Isn't there a need for widgets/controls for the
2 channel case as well?
It's also not good practice to mix the initialization of max98090 with a
function with an explicit 98373 prefix. it's hard to maintain and
error-prone. You might as well duplicate the function, if it's not used
it will be removed while linking.

I am still relatively confused since you still have two alternatives for
topology but you described three configurations.
