[PATCH v2 0/8] ASoC: soc-pcm cleanup step5

[Kuninori Morimoto]

Hi Mark

These are v2 of soc-pcm cleanup step5.
These are based on latest for-5.7 branch.
Mainly v2 fixed the points reviewed in v1.

[7/8] patch might exchange the behavior

Kuninori Morimoto (8):
  1) ASoC: soc-pcm: use defined stream
  2) ASoC: soc-pcm: remove duplicate be check from dpcm_add_paths()
  3) ASoC: soc-pcm: move dpcm_fe_dai_close()
  4) ASoC: soc-pcm: add dpcm_fe_dai_cleanup()
  5) ASoC: soc-pcm: use snd_soc_dai_get_pcm_stream() at dpcm_set_fe_runtime()
  6) ASoC: soc-pcm: check DAI's activity more simply
  7) ASoC: soc-pcm: Do Digital Mute for both CPU/Codec in same timing.
  8) ASoC: soc-pcm: tidyup dulicate handing at dpcm_fe_dai_startup()

[PATCH v2 1/8] ASoC: soc-pcm: use defined stream

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Many functions defines "stream = substream->stream", but
some of them is using "substream->stream" instead of "stream".
It is pointless. This patch uses defined stream.

[PATCH v2 2/8] ASoC: soc-pcm: remove duplicate be check from dpcm_add_paths()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

dpcm_add_paths() checks returned be from dpcm_get_be()

	static int dpcm_add_paths(...)
	{
		...
		for_each_dapm_widgets(list, i, widget) {
			...
			be = dpcm_get_be(...);
			...
			/* make sure BE is a real BE */
=>			if (!be->dai_link->no_pcm)
				continue;
			...
		}
		...
	}

But, dpcm_get_be() itself is checking it already.

		...

=>			if (!be->dai_link->no_pcm)
				continue;
			...

=>				return be;
		}

		return NULL
	}

This patch removes duplicate check

[PATCH v2 4/8] ASoC: soc-pcm: add dpcm_fe_dai_cleanup()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

dpcm_fe_dai_close() and error case of dpcm_fe_dai_open()
need to do same cleanup operation.
To avoid duplicate code, this patch adds dpcm_fe_dai_cleanup()
and use it.

[PATCH v2 6/8] ASoC: soc-pcm: check DAI's activity more simply

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

DAI is counting its activity, and both playback/capture directional
activity. When considering mute, DAI's activity is enough instead of
caring both playback/capture.
This patch makes mute check simply.

I noticed that it calls snd_soc_dai_digital_mute(xxx, substream->stream).
This means, it want to call mute for each Playback/Capture "last user".
This patch was total wrong.

Mark, [6/8] is wrong. maybe I need to reconsider [7/8].
Can you please ignore these ?
Please let me know if you need v3

Thank you for your help !!
