FWIW we use the "snd_codec_conf" stuff to add a prefix for each 
amplifier, so that the controls are not mixed up between instances of 
the same amp, see e.g.

	
static struct snd_soc_codec_conf codec_conf[] = {
	{
		.dev_name = "sdw:0:25d:711:0:1",
		.name_prefix = "rt711",
	},
	{
		.dev_name = "sdw:1:25d:1308:0:0",
		.name_prefix = "rt1308-1",
	},
	{
		.dev_name = "sdw:2:25d:1308:0:2",
		.name_prefix = "rt1308-2",
	},
	{
		.dev_name = "sdw:3:25d:715:0:1",
		.name_prefix = "rt715",
	},
};
