alsactl: init - add -U option to disable UCM based init

alsa-project/alsa-utils pull request #60 was edited from ahlinc: The reason is to use it with internal init extra commands like: alsactl -U -E CMD=info init Currently, if there is a valid UCM config for a card the alsactl command exits silently on the init command and don't execute any extra commands because that commands defined in a common init path file _init/00main_ that don't used in case of UCM did the job.

[PATCH] ASoC: soc-pcm: ignore un-needed mutex_unlock() case on soc_pcm_open()
by Kuninori Morimoto 02 Oct '20

02 Oct '20

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> commit 140a4532cdb8c ("ASoC: soc-pcm: add soc_pcm_clean() and call it from soc_pcm_open/close()") switch to call soc_pcm_clean() on soc_pcm_open() when rollback case. But, it uses "goto err" (A) *before* mutex_lock() (B) when error of snd_soc_pcm_component_pm_runtime_get(). The mutex_unlock() (C) is not needed in such case. This patch fix it. static int soc_pcm_open(...) { ... ret = snd_soc_pcm_component_pm_runtime_get(rtd, substream); if (ret < 0) (A) goto err; (B) mutex_lock_nested(...); ... err: (C) mutex_unlock(..); ... } Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> --- sound/soc/soc-pcm.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/sound/soc/soc-pcm.c b/sound/soc/soc-pcm.c index 09e8d703a502..5d538520e2cf 100644 --- a/sound/soc/soc-pcm.c +++ b/sound/soc/soc-pcm.c @@ -706,7 +706,7 @@ static int soc_pcm_open(struct snd_pcm_substream *substream) ret = snd_soc_pcm_component_pm_runtime_get(rtd, substream); if (ret < 0) - goto err; + goto pm_err; mutex_lock_nested(&rtd->card->pcm_mutex, rtd->card->pcm_subclass); @@ -786,7 +786,7 @@ static int soc_pcm_open(struct snd_pcm_substream *substream) snd_soc_runtime_activate(rtd, substream->stream); err: mutex_unlock(&rtd->card->pcm_mutex); - +pm_err: if (ret < 0) soc_pcm_clean(substream, 1); -- 2.25.1

[PATCH] ASoC: wm_adsp: Pass full name to snd_ctl_notify
by Charles Keepax 02 Oct '20

02 Oct '20

From: Adam Brickman <Adam.Brickman(a)cirrus.com> A call to wm_adsp_write_ctl() could cause a kernel crash if it does not retrieve a valid kcontrol from snd_soc_card_get_kcontrol(). This can happen due to a missing control name prefix. Then, snd_ctl_notify() crashes when it tries to use the id field. Modified wm_adsp_write_ctl() to incorporate the name_prefix (if applicable) such that it is able to retrieve a valid id field from the kcontrol once the platform has booted.
