[PATCH v1 0/2] ASoC: codecs: ES8326: change members of private structure
by Zhang Yi 06 Mar '24

06 Mar '24

We found that using 0x45 as the default value for interrupt-clk would cause a headset detection error.So we took 0x00 as the default value for interrupt-clk and passed the test. We removed mic1-src and mic2-src, which were not used. *** BLURB HERE *** Zhang Yi (2): ASoC: codecs: ES8326: Changing members of private structure ASoC: codecs: ES8326: change support for ES8326 .../bindings/sound/everest,es8326.yaml | 22 ++----------------- sound/soc/codecs/es8326.c | 18 +-------------- 2 files changed, 3 insertions(+), 37 deletions(-) -- 2.17.1

[PATCH 0/5] ASoC: Harden DAPM route checks and Intel fixes
by Cezary Rojewski 06 Mar '24

06 Mar '24

Set of loosely connected patches. Most impactful change is dropping any permisiveness when snd_soc_dapm_add_routes() fails in soc-topology.c To do it safely, disable route checks for all skylake-driver boards. Relevant background: Since commit daa480bde6b3 ("ASoC: soc-core: tidyup for snd_soc_dapm_add_routes()") route checks are no longer permissive. Probe failures for Intel boards have been partially addressed by commit a22ae72b86a4 ("ASoC: soc-core: isable route checks for legacy devices") and its follow up but only skl_nau88l25_ssm4567.c is patched. The rest of the boards still need fixing. After that, removal of copy-pastas found in ssm4567.c and redundant code in i2s_test.c for avs-boards.

[PATCH] ASoC: soc-card: Fix missing locking in snd_soc_card_get_kcontrol()
by Richard Fitzgerald 06 Mar '24

06 Mar '24

snd_soc_card_get_kcontrol() must be holding a read lock on card->controls_rwsem while walking the controls list. Compare with snd_ctl_find_numid(). The existing function is renamed snd_soc_card_get_kcontrol_locked() so that it can be called from contexts that are already holding card->controls_rwsem (for example, control get/put functions). There are few direct or indirect callers of snd_soc_card_get_kcontrol(), and most are safe. Three require changes, which have been included in this patch: codecs/cs35l45.c: cs35l45_activate_ctl() is called from a control put() function so is changed to call snd_soc_card_get_kcontrol_locked(). codecs/cs35l56.c: cs35l56_sync_asp1_mixer_widgets_with_firmware() is called from control get()/put() functions so is changed to call snd_soc_card_get_kcontrol_locked(). fsl/fsl_xcvr.c: fsl_xcvr_activate_ctl() is called from three places, one of which already holds card->controls_rwsem: 1. fsl_xcvr_mode_put(), a control put function, which will already be holding card->controls_rwsem. 2. fsl_xcvr_startup(), a DAI startup function. 3. fsl_xcvr_shutdown(), a DAI shutdown function. To fix this, fsl_xcvr_activate_ctl() has been changed to call snd_soc_card_get_kcontrol_locked() so that it is safe to call directly from fsl_xcvr_mode_put(). The fsl_xcvr_startup() and fsl_xcvr_shutdown() functions have been changed to take a read lock on card->controls_rsem() around calls to fsl_xcvr_activate_ctl(). While this is not very elegant, it keeps the change small, to avoid this patch creating a large collateral churn in fsl/fsl_xcvr.c. Analysis of other callers of snd_soc_card_get_kcontrol() is that they do not need any changes, they are not holding card->controls_rwsem when they call snd_soc_card_get_kcontrol(). Direct callers of snd_soc_card_get_kcontrol(): fsl/fsl_spdif.c: fsl_spdif_dai_probe() - DAI probe function fsl/fsl_micfil.c: voice_detected_fn() - IRQ handler Indirect callers via soc_component_notify_control(): codecs/cs42l43: cs42l43_mic_shutter() - IRQ handler codecs/cs42l43: cs42l43_spk_shutter() - IRQ handler codecs/ak4118.c: ak4118_irq_handler() - IRQ handler codecs/wm_adsp.c: wm_adsp_write_ctl() - not currently used Indirect callers via snd_soc_limit_volume(): qcom/sc8280xp.c: sc8280xp_snd_init() - DAIlink init function ti/rx51.c: rx51_aic34_init() - DAI init function I don't have hardware to test the fsl/*, qcom/sc828xp.c, ti/rx51.c and ak4118.c changes. Backport note: The fsl/, qcom/, cs35l45, cs35l56 and cs42l43 callers were added since the Fixes commit so won't all be present on older kernels.

Alsamixer is exiting upon receiving some keys, such as volume control ones
by GitHub issues - opened 06 Mar '24

06 Mar '24

alsa-project/alsa-utils issue #255 was opened from Porkepix: When in an environment not intercepting those keys (usually managed by your compositor/window manager), upon receiving some keycodes such as volume up or down, alsamixer is exiting and writing the UTF-8 keycode inside the terminal while it shouldn't. Examples: Mute key > 440u Volume down key > 438u Volume up key > 439u Curiously enough, the microphone mute one doesn't do anything. These should at the very least not exit alsamixer. A bonus would be, when they're not intercepted, to actually use them to apply mutes and volumes up/down.

[PATCH v1] slimbus: stream: Add null pointer check to prevent crash
by Viken Dadhaniya 06 Mar '24

We are facing crash due to null pointer dereference of stream in slim_stream_disable(). there is a possible scenario where client driver is calling slimbus stream APIs in incorrect sequence and it might lead to null pointer access of the stream in slimbus enable/disable/prepare/unprepare/free functions. Fix this issue by adding null pointer check of the stream before accessing in all stream API’s exposed to client.

[PATCH] ASoC: da7219: read fmw property to get mclk for non-dts systems
by cujomalainey＠chromium.org 05 Mar '24

05 Mar '24

From: Akshu Agrawal <akshu.agrawal(a)amd.com> Non-dts based systems can use ACPI DSDT to pass on the mclk to da7219. This enables da7219 mclk to be linked to system clock. Enable/Disable of the mclk is already handled in the codec so platform drivers don't have to explicitly do handling of mclk.
