[alsa-devel] [PATCH 1/2] ASoC: Intel: Add stream direction for pcm-module map
A DAI may have 2 streams(playback/capture) and different modules may be needed for them respectively, so we need add a stream direction here, the combination(dai_id + stream) can tell us which module we really need here.

There may be 2 pcm streams for a same DAI at most, and these 2 streams should have different hsw_pcm_data, e.g. they have different persistent data, so here we need split hsw_pcm_data for playback and capture, to make sure they won't be mixed and keep cleaned.

This doesn't seem to apply against current code, can you please check and resend?
