ASoC: cs35l56: Use complete_all() to signal init_completion

2026-08-03T09:17:09+00:00

[ Upstream commit e0bffb63a2eda0af82ed7e6357ac67c2db990c21 ] In cs35l56_init() use complete_all() to signal init_completion instead of complete(). cs35l56_init() was signaling init_completion using the complete() function. This only releases ONE waiter. If cs35l56_component_probe() was called multiple times the first time would consume that one signal, then future calls would timeout waiting for the completion. This could happen if: - The component is probed, removed, then probed again without the cs35l56 module being removed. - A call to component_probe() returns an error and ASoC calls it again later. It should use complete_all() so that after it has been signaled it will allow any code that waits on it to continue immediately. The one case where the driver must wait for initialization to run again is when waiting for a reboot after firmware download, and here the code correctly calls reinit_completion() first.

ASoC: cs35l56: Fix potential probe() deadlock

2026-08-03T09:17:09+00:00

[ Upstream commit 93c2a8ea2454b7b14eb378a58cad8a83c0ffc903 ] On I2C/SPI call cs35l56_init() before calling snd_soc_register_component() to prevent the potential for a deadlock on init_completion. For most buses all the hardware would be ready when probe() returns, but on SoundWire, probe() must return before the SoundWire bus driver will enumerate the device. All access to the registers must be deferred until the driver receives an ATTACHED notification. But anything that could return -EPROBE_DEFER must be called during probe, and that includes snd_soc_register_component(). Because of that, on SoundWire the ASoC component can be created before the registers are accssible, so cs35l56_component_probe() waits for init_completion to signal that the registers are accessible. On I2C/SPI this 2-stage startup isn't required so their probe() functions simply called cs35l56_common_probe() and then cs35l56_init(). The problem with this was that snd_soc_register_component() was still called early. If this triggered ASoC to create the card, ASoC would call cs35l56_component_probe() which waits on init_completion - but this would be running inside the cs35l56 driver probe() so blocking it from reaching the code that signals init_completion, causing a deadlock.

ASoC: cs35l56: Don't use devres to unregister component

2026-08-03T09:17:09+00:00

[ Upstream commit bee87cf0f1248c0f20710d7a79df41fe892d9f88 ] Manually call snd_soc_unregister_component() from cs35l56_remove() instead of using devres cleanup. This ensures that the component is destroyed before cs35l56_remove() starts cleanup of anything the component code could be using. Devres cleanup happens after the driver remove() callback, so if snd_soc_register_component() is used, it will not be destroyed until after cs35l56_remove() has returned. But there is some cleanup that must be done in cs35l56_remove(), or wrapped in a custom devres cleanup handler to ensure correct ordering. The simplest option is to call snd_soc_unregister_component() at the start of cs35l56_remove().

ASoC: bt-sco: fix duplicate DAPM widget names for wideband DAI

2026-08-03T09:17:09+00:00

[ Upstream commit 0b604e886ece11b71c4daaeccc512c784b89b014 ] The bt-sco-pcm-wb DAI uses the same stream_name strings as bt-sco-pcm ("Playback" and "Capture"). This causes duplicate DAPM AIF widget names within the same component, leading to debugfs warnings: debugfs: 'Playback' already exists in 'dapm' debugfs: 'Capture' already exists in 'dapm' Give the wideband DAI distinct stream names ("WB Playback" and "WB Capture") and add corresponding DAPM AIF widgets and routes for them.

ASoC: tas2781: bound firmware description string parsing

2026-08-03T09:17:09+00:00

[ Upstream commit bc889dfcea9294a1eae7f8e2f3573a90764ae4d0 ] The TAS2781 firmware parser reads several variable-length description strings with strlen() before checking that the string terminator is present inside the firmware blob. A malformed firmware image without a NUL terminator can therefore make the parser walk past the end of the firmware buffer before the later size checks run. Add a small bounded string-length helper and use it for all description fields that are parsed from the firmware buffer. Keep the existing size checks for the fixed bytes that follow each string.

ASoC: tas2562: fix deprecated 'shut-down' GPIO always cleared after lookup

2026-08-03T09:17:03+00:00

[ Upstream commit 3238c634725afbb2a137fdda762208510828f71d ] In tas2562_parse_dt(), the fallback lookup for the deprecated "shut-down" GPIO property is broken due to a missing pair of braces. The code intends to reset sdz_gpio to NULL only when the lookup returns an error that is not -EPROBE_DEFER (so the driver gracefully continues without a GPIO). However, without braces the statement: tas2562->sdz_gpio = NULL; falls outside the IS_ERR() check and is executed unconditionally for every path through the if block, including a successful GPIO lookup. This means any device using the deprecated 'shut-down' DT property will always have sdz_gpio == NULL after probe, making the GPIO completely non-functional. Fix this by adding the missing braces to scope the NULL assignment inside the IS_ERR() branch, matching the pattern already used for the primary 'shutdown' GPIO lookup above.

ASoC: tlv320aic3x: restrict CLKDIV bypass Q values in dual-rate mode

[ Upstream commit fdf043f5f3bae150b678feae3d7bb1beed87ec14 ] The datasheet documents that when the PLL is disabled and dual-rate mode is enabled, only Q values {4, 8, 9, 12, 16} are valid for the CLKDIV bypass path; all other Q values produce invalid bitclock output. The existing loop iterates Q from 2 to 17 without this restriction, causing silent audio failure when an out-of-spec Q is picked. Restrict the Q search to the allowed set in dual-rate mode.
