ASoC: export DPCM runtime update functions

2020-03-12T13:30:38Z

This makes DPCM runtime update functions available for external calling. As an example, virtualised ASoC component drivers may need to call these when managing shared DAPM routes that are used by more than one driver (i.e. when host driver and guest drivers have a DAPM path from guest PCM to host DAI where some parts are owned by host driver and others by guest driver).

ASoC: soc-pcm: move dpcm_path_put() to soc-pcm.c

2020-02-24T21:18:32Z

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(); ... } (C) snd_soc_dapm_dai_get_connected_widgets(..., **list, ...) { ... dapm_widget_list_create(list, ...); ... } (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().

ASoC: soc-pcm: remove snd_soc_dpcm_be_get/set_state()

2020-02-18T23:37:02Z

No one is using snd_soc_dpcm_be_get/set_state(). If it exists only by assumption that "it may be necessary someday", let's remove it now. Otherwise code maintenance will be difficult. We can revive it when we really needed it. Let's remove it, so far.

ASoC: soc-dpcm: tidyup for_each_dpcm_xx() macro

2019-10-25T10:06:35Z

for_each_dpcm_xx() macro is using "dpcm" as parameter (1), but, it is also struct member (2). #define for_each_dpcm_fe(be, stream, dpcm) \ list_for_each_entry(dpcm, &(be)->dpcm[stream]...) ^^^^(1) ^^^^(2) Thus, it will be compile error if user not used "dpcm" as parameter for_each_dpcm_fe(be, stream, dp) ^^ This patch fixup it.

ASoC: soc-core: define soc_dpcm_debugfs_add() for non CONFIG_DEBUG_FS

2019-08-08T19:56:57Z

soc_dpcm_debugfs_add() is implemented at soc-pcm.c under CONFIG_DEBUG_FS. Thus, soc-core.c which is only user of it need to use CONFIG_DEBUG_FS, too. This patch defines soc_dpcm_debugfs_add() for non CONFIG_DEBUG_FS case. Then, we can remove #ifdef CONFIG_DEBUG_FS from soc-core.c Signed-off-by: Kuninori Morimoto Link: https://lore.kernel.org/r/875zn9ahnv.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

2015-04-09T10:32:29Z

Failing to register the debugfs entries is not fatal and will not affect normal operation of the sound card. Don't abort the card registration if soc_dpcm_debugfs_add() fails. Signed-off-by: Lars-Peter Clausen Signed-off-by: Mark Brown
