[PATCH] ASoC: SOF: icp3-dtrace: Fix wrong kfree() usage
by Kamil Duljas 28 Nov '23

[PATCH] ASoC: codecs: lpass-tx-macro: set active_decimator correct default value
by Neil Armstrong 28 Nov '23

28 Nov '23

The -1 value for active_decimator[dai_id] is considered as "not set", but at probe the table is initialized a 0, this prevents enabling the DEC0 Mixer since it will be considered as already set. Initialize the table entries as -1 to fix tx_macro_tx_mixer_put().

tlv320aic3x: Failed to init class D
by Marc Kleine-Budde 28 Nov '23

28 Nov '23

Hello, we are using an I2C connected ti,tlv320aic3007. During probe, regmap_register_patch() returns -6, which leads to the error message: "tlv320aic3x 2-0018: Failed to init class D: -6". I think this is because the codec is still in reset and does not respond to the I2C transfers. How to get rid of the error message? Power on the codec, just to write the register sequence or don't print the error message on "-6"? regards, Marc -- Pengutronix e.K. | Marc Kleine-Budde | Embedded Linux | https://www.pengutronix.de | Vertretung Nürnberg | Phone: +49-5121-206917-129 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-9 |

[PATCH 0/2] ALSA/ASoC: hdmi/hdac_hda: Conditionally register dais
by Peter Ujfalusi 28 Nov '23

28 Nov '23

Hi, Each instance of the hdac_hda registers DAIs to be used for analog and HDMI audio. When the system have more than one HDA codec - like most devices then the kernel log will include the following warning prints: snd_hda_codec_realtek ehdaudio0D0: ASoC: sink widget AIF1TX overwritten snd_hda_codec_realtek ehdaudio0D0: ASoC: source widget AIF1RX overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: sink widget hifi3 overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: sink widget hifi2 overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: sink widget hifi1 overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: source widget Codec Output Pin1 overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: sink widget Codec Input Pin1 overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: sink widget Analog Codec Playback overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: sink widget Digital Codec Playback overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: sink widget Alt Analog Codec Playback overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: source widget Analog Codec Capture overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: source widget Digital Codec Capture overwritten skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: source widget Alt Analog Codec Capture overwritten These are printed when the second instance of the hdac_hda is probing since it is re-registering the DAIs with the same name. Using some clever way of prefixing might solve the issue but that would need non backwards compatible changes to topology files. Pragmatically the hdac_hda instance fro the normal codec should not register DAIs for HDMI and the hdac_hda instance for the HDMI should not register DAIs for the analog codec - for example on a SDW device where we have HDA-HDMI and sdw codecs. To keep the hdac_hda vendor neutral (altrough it is only used on Intel platforms afaik) add a helper function to answer the question: is this codec HDMI? Use the new helper to decide which sets of DAIs to register for the probing hdac_hda instance.

[PATCH] soundwire: stream: fix NULL pointer dereference for multi_link
by Krzysztof Kozlowski 28 Nov '23

28 Nov '23

If bus is marked as multi_link, but number of masters in the stream is not higher than bus->hw_sync_min_links (bus->multi_link && m_rt_count >= bus->hw_sync_min_links), bank switching should not happen. The first part of do_bank_switch() code properly takes these conditions into account, but second part (sdw_ml_sync_bank_switch()) relies purely on bus->multi_link property. This is not balanced and leads to NULL pointer dereference: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 ...
