Don't we need the same change of name_prefix for
soc-acpi-intel-mtl-match.c? I see this in the existing code:

static const struct snd_soc_acpi_adr_device cs35l56_1_adr[] = {
	{
		.adr = 0x00013701FA355601ull,
		.num_endpoints = 1,
		.endpoints = &spk_r_endpoint,
		.name_prefix = "cs35l56-8"
	},
	{
		.adr = 0x00013601FA355601ull,
		.num_endpoints = 1,
		.endpoints = &spk_3_endpoint,
		.name_prefix = "cs35l56-7"
	}
};

static const struct snd_soc_acpi_adr_device cs35l56_2_adr[] = {
	{
		.adr = 0x00023301FA355601ull,
		.num_endpoints = 1,
		.endpoints = &spk_l_endpoint,
		.name_prefix = "cs35l56-1"
	},
	{
		.adr = 0x00023201FA355601ull,
		.num_endpoints = 1,
		.endpoints = &spk_2_endpoint,
		.name_prefix = "cs35l56-2"
	}
};
