ASoC: amd: acp: fix card name length warning in SOF SoundWire machine driver

2026-09-16T19:08:19Z

The ALSA snd_card driver[] field is 16 bytes (including the NUL terminator), leaving 15 usable characters. The SOF framework prepends a "sof-" prefix when registering the card, so card->name = "amd-soundwire" becomes driver name "sof-amd-soundwire" which is 17 characters and overflows the driver[16] buffer, triggering a kernel warning. Fix by shortening the card name to "amd-sdw"; the resulting driver name "sof-amd-sdw" fits within the 15-character limit.

ASoC: amd: acp: fix ffs() operator precedence for SoundWire link ID

2026-09-16T19:08:18Z

ffs(link_mask - 1) computes ffs on (link_mask - 1) instead of subtracting 1 from the result of ffs(link_mask). For a typical power-of-2 link_mask this returns the wrong link ID, causing cpu_pin_id lookup to select the incorrect SoundWire manager. Fix the operator precedence to ffs(link_mask) - 1 in both acp-sdw-sof-mach.c and acp-sdw-legacy-mach.c.

ASoC: amd: acp: refactor codec config count in SOF SoundWire machine driver

2026-09-16T19:08:17Z

num_devs was used both as the endpoint count and as the output for asoc_sdw_parse_sdw_endpoints(), which overwrites it with the codec configuration count. Introduce a separate num_confs variable to hold the codec conf count so the two values remain distinct across codec_conf allocation and card->num_configs assignment.

ASoC: amd: acp: bounds-check SoundWire link ID in machine drivers

2026-09-16T19:08:16Z

Add a bounds check in create_sdw_dailink() to validate that the SoundWire link ID derived from link_mask does not exceed the maximum supported by the platform. If the link ID is out of range or link_mask is zero, log an error and return -EINVAL to prevent accessing invalid CPU pin ID tables. Applied to both acp-sdw-sof-mach.c and acp-sdw-legacy-mach.c.

ASoC: amd: acp-da7219-max98357a: don't bind on Raven/Picasso boards

2026-09-08T14:59:06Z

The "AMDI5682" ACPI HID is matched by two AMD ASoC machine drivers: cz-da7219-max98357a (this driver, Carrizo/Stoney) and acp3x-alc5682-max98357 (Raven/Picasso). cz-da7219-max98357a is linked first and probes the platform device first; its DAI links reference the Stoney ACP, which is absent on Raven/Picasso, so its card can never be instantiated there. This was harmless until commit 42d99857d6f0 ("ASoC: core: Move all users to deferrable card binding"): devm_snd_soc_register_card() now returns 0 for a card left pending instead of propagating -EPROBE_DEFER, so cz_probe() succeeds and permanently binds AMDI5682. acp3x-alc5682-max98357 never binds and the internal speakers and headphone jack get no card. Detect Raven/Picasso (and later) by the ACP3.x audio coprocessor's dedicated PCI function (1022:15e2); Carrizo/Stoney reach the ACP through the GPU driver and have no such device. Return -ENODEV so the driver core continues probing AMDI5682 with acp3x-alc5682-max98357.

ASoC: amd: yc: add quirk for Acer Nitro AN17-41 internal mic

2026-09-07T21:00:25Z

The Acer Nitro AN17-41 uses "RB" as its board vendor and has no entry in yc_acp_quirk_table, so acp6x_probe() finds no DMI match, registers no card, and the internal digital microphone records only silence. Add a quirk entry for it so the DMIC is enabled. Signed-off-by: Aaron Welwood Link: https://patch.msgid.link/20260907031738.17257-1-abwelwood@gmail.com Signed-off-by: Mark Brown

Merge tag 'asoc-fix-v7.3-merge-window' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2026-08-27T14:15:47Z

ASoC: Fixes for v7.3 A fairly big batch of fixes that came in during the merge window. There's a lot of quirks for x86 systems and a bunch of driver specific fixes, the most critical being the fixes for Tegra's register definitions. It turned out that they had been relying on the regmap default handling bugs that were fixed in v7.2 and so audio was fairly badly broken, unfortunately the issue wasn't noticed in time for release.
