Hi Mark

These are soc-pcm cleanup step4.

[01/13] - [06/13] are posted but not yet accepted patches. To avoid conflict, I merged these into step4. These patches are already received Reviewed-by from Pierre-Louis.

New subject: [PATCH 07/13] ASoC: soc-pcm: add snd_soc_dai_get_pcm_stream()

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

DAI driver has playback/capture stream. OTOH, we have SNDRV_PCM_STREAM_PLAYBACK/CAPTURE. Because of this kind of implementation, ALSA SoC needs to have many verbose code.

To solve this issue, this patch adds snd_soc_dai_get_pcm_stream() macro to get playback/capture stream pointer from stream.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Wed, 19 Feb 2020 15:56:30 +0900 Subject: [PATCH] ASoC: soc-pcm: add snd_soc_dai_get_pcm_stream()

DAI driver has playback/capture stream. OTOH, we have SNDRV_PCM_STREAM_PLAYBACK/CAPTURE. Because of this kind of implementation, ALSA SoC needs to have many verbose code.

To solve this issue, this patch adds snd_soc_dai_get_pcm_stream() macro to get playback/capture stream pointer from stream.

New subject: [PATCH 08/13] ASoC: soc-pcm: cleanup soc_pcm_apply_msb()

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

soc_pcm_apply_msb() apply msb for CPU/Codec, but, it has duplicate code. The difference is only SNDRV_PCM_STREAM_PLAYBACK and SNDRV_PCM_STEAM_CAPTURE.

It is very verbose and duplicate code. This patch simplify code by using snd_soc_dai_get_pcm_stream().

New subject: [PATCH 11/13] ASoC: soc-pcm: move dpcm_path_put() to soc-pcm.c

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

dpcm_path_put() (A) is calling kfree(*list). The freed list is created by dapm_widget_list_create() (B) which is called from snd_soc_dapm_dai_get_connected_widgets() (C) which is called from dpcm_path_get() (D).

(B) dapm_widget_list_create(**list, ...) { ... => *list = kzalloc(); ... }

(D) dpcm_path_get(..., **list) { ... snd_soc_dapm_dai_get_connected_widgets(..., list, ...); ... }

(A) dpcm_path_put(**list) { => kfree(*list); }

This kind of unbalance code is very difficult to read/understand. To avoid this issue, this patch adds each missing paired function dapm_widget_list_free() for dapm_widget_list_create() (B), and snd_soc_dapm_dai_free_widgets() for snd_soc_dapm_dai_get_connected_widgets() (C).

This patch uses these, and moves dpcm_path_put() next to dpcm_path_get().

New subject: [PATCH 13/13] ASoC: soc-pcm: add dpcm_create/remove_debugfs_state()

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

soc-pcm.c has implementation which depends on CONFIG_DEBUG_FS. But, we don't want to have random #ifdef. This patch adds dpcm_create/remove_debugfs_state() and care it.
