Routes and codec conf are different things, not following how you can
merge them?

Wondering if you are referring to a different array, i.e.

static struct snd_soc_codec_conf max_98390_codec_conf[]

static struct snd_soc_codec_conf max_98390_4spk_codec_conf[]

I just merge two arrays, max_98373_dapm_routes and max_98390_4spk_codec_conf,
since the first two entries are the same.

Later in max_98390_set_codec_conf() function we will set the num_configs with
number of amplifiers.

void max_98390_set_codec_conf(struct snd_soc_card *card)
{
unsigned int num_codecs = get_num_codecs(MAX_98390_ACPI_HID);

card->codec_conf = max_98390_codec_conf;

switch (num_codecs) {
case 2:
case 4:
card->num_configs = num_codecs;

Yes I mean max_98390_codec_conf and max_98390_4spk_codec_conf. Sorry
for the mistake.

I believe you have struct device pointer available, use dev_err().
