[PATCH] ASoC: mediatek: mt8183: delete some unreachable code
by Dan Carpenter 11 Dec '20

11 Dec '20

This has a goto followed by an unreachable return statement. The goto is correct because it cleans up so the current runtime behavior is fine. Let's delete the unreachable return statement.

[PATCH v3 0/2] ASoC: rt1015p: delay 300ms for waiting calibration
by Tzung-Bi Shih 11 Dec '20

11 Dec '20

The 1st patch moves SDB control from DAI ops trigger to DAPM event (per review comments in v1). The 2nd patch adds the 300ms delay for waiting calibration. Changes from v2: - Use gpiod_set_value_cansleep() instead of gpiod_set_value().

[PATCH 1/2] ASoC: topology: Fix wrong size check
by Amadeusz Sławiński 11 Dec '20

11 Dec '20

Dan reported that smatch reports wrong size check and after analysis it is confirmed that we are comparing wrong value: pointer size instead of array size. However the check itself is problematic as in UAPI header there are two fields: struct snd_soc_tplg_enum_control { (...) char texts[SND_SOC_TPLG_NUM_TEXTS][SNDRV_CTL_ELEM_ID_NAME_MAXLEN]; __le32 values[SND_SOC_TPLG_NUM_TEXTS * SNDRV_CTL_ELEM_ID_NAME_MAXLEN / 4]; the texts field is for names and the values one for values assigned to those named fields, after analysis it becomes clear that there is quite a lot overhead values than we may possibly name. So instead of changing check to ARRAY_SIZE(ec->values), as it was first suggested, use hardcoded value of SND_SOC_TPLG_NUM_TEXTS.

[PATCH] ASoC: wm_adsp: remove "ctl" from list on error in wm_adsp_create_control()
by Dan Carpenter 11 Dec '20

11 Dec '20

The error handling frees "ctl" but it's still on the "dsp->ctl_list" list so that could result in a use after free. Remove it from the list before returning.

[PATCH] ALSA: hda/hdmi: packet buffer index must be set before reading value
by Kai Vehmanen 11 Dec '20

11 Dec '20

The check for infoframe transmit status in hdmi_infoframe_uptodate() makes the assumption that packet buffer index is set to zero. Align code with specification and explicitly set the index before AC_VERB_GET_HDMI_DIP_XMIT. The packet index setting affects both DIP-Data and DIP-XmitCtrl verbs. There are no known cases where the old implementation has caused driver to work incorrectly. This change is purely based on code review against the specification (HDA spec rev1.0a).

[PATCH] ALSA: hda/hdmi: always print pin NIDs as hexadecimal
by Kai Vehmanen 11 Dec '20

11 Dec '20

The debug prints from patch_hdmi.c are not aligned with HDA common code in hda_codec.c nor with other HDA codec drivers. To align with rest of the codebase, use hexadecimal formatting whenever printing value of a HDA NID. Also refer to NIDs with capital letters in traces as is done other modules. This presentation is also aligned with the formatting used in HDA codec procfs entry.

[PATCH] ALSA: usb-audio: Fix control 'access overflow' errors from chmap
by Takashi Iwai 11 Dec '20

11 Dec '20

The current channel-map control implementation in USB-audio driver may lead to an error message like "control 3:0:0:Playback Channel Map:0: access overflow" when CONFIG_SND_CTL_VALIDATION is set. It's because the chmap get callback clears the whole array no matter which count is set, and rather the false-positive detection. This patch fixes the problem by clearing only the needed array range at usb_chmap_ctl_get().

How to annotate USB jacks without jack detection?
by Kai-Heng Feng 11 Dec '20

11 Dec '20

Hi, There are some UAC1 devices come with jacks, but without jack detection ability. And many USB/Thunderbolt docks are equipped with such USB device. Userspace like PulseAudio automatically switch to USB audio when they gets plugged. However, auto-switching to UAC1 device can be problematic because it may not connected to any headset or speaker. So I wonder what's the best way to let userspace know the USB device is a jack without jack detection ability? Through sysfs or dedicated UCM conf? Kai-Heng
