Now we have broken what was working before,

This should proably be

if (is_cdc_dma_port(dai_id))
	err = lpass_platform_cdc_dma_mmap(component, substream, vma);
else
	err = snd_pcm_lib_default_mmap(substream, vma);

return err;

Should this be:

if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK) {
	if (is_cdc_dma_port(dai_id))
		ret = copy_from_user_toio(dma_buf, buf, bytes);
	else
		ret = copy_from_user((void __force *)dma_buf, buf, bytes);
} else if (substream->stream == SNDRV_PCM_STREAM_CAPTURE) {
	if (is_cdc_dma_port(dai_id))
		ret = copy_to_user_fromio(buf, dma_buf, bytes);
	else
		ret = copy_to_user(buf, dma_buf, bytes);
}

return ret;
