Yes, sorry I didn't get your point. I guess I tought that it's irrelevant, what
the soc_card driver actually does. But it actually does this:

	switch (wl1273_get_codec_mode(codec)) {
	case WL1273_MODE_FM_RX:
	case WL1273_MODE_FM_TX:
		fmt =	SND_SOC_DAIFMT_I2S |

	case WL1273_MODE_BT:

		return -EINVAL;

	r = snd_soc_dai_set_fmt(cpu_dai, fmt);
