[PATCH v2 resend 0/6] ASoC: soc-pcm cleanup step5

[Kuninori Morimoto]

Hi Mark

These are v2 resend of soc-pcm cleanup step5.
1) - 4) are rebased to latest for-5.7 branch.
5) - 6) are remaked of previous [6/8], [7/8] which were mistaken patch.

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

[PATCH v2 resend 1/6] ASoC: soc-pcm: move dpcm_fe_dai_close()

[Kuninori Morimoto]

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

move dpcm_fe_dai_close() next to dpcm_fe_dai_open().
This is prepare for dpcm_fe_dai_open() cleanup

[PATCH v2 resend 2/6] 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 resend 5/6] ASoC: soc-pcm: check DAI's activity more simply

[Kuninori Morimoto]

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

soc_pcm_hw_free() want to call snd_soc_dai_digital_mute()
if it was last user of Playback or Capture.

	bool playback = substream->stream == SNDRV_PCM_STREAM_PLAYBACK;
	int playback_active = dai->stream_active[SNDRV_PCM_STREAM_PLAYBACK];
	int capture_active  = dai->stream_active[SNDRV_PCM_STREAM_CAPTURE];

	if ((playback  && playback_active == 1) ||
	    (!playback && capture_active  == 1))
		snd_soc_dai_digital_mute(...)

But it is same as

	int active = dai->stream_active[substream->stream];

	if (active == 1)
		snd_soc_dai_digital_mute(...)

This patch simplify the code.

[Mark Brown]

The patch

   ASoC: soc-pcm: Do Digital Mute for both CPU/Codec in same timing.

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
