ASoC: SOF: ipc4-topology: Allow bytes controls without initial payload

2026-04-02T11:23:17+00:00

commit d40a198e2b7821197c5c77b89d0130cc90f400f5 upstream. It is unexpected, but allowed to have no initial payload for a bytes control and the code is prepared to handle this case, but the size check missed this corner case. Update the check for minimal size to allow the initial size to be 0.

ASoC: sma1307: fix double free of devm_kzalloc() memory

2026-04-02T11:23:17+00:00

commit fe757092d2329c397ecb32f2bf68a5b1c4bd9193 upstream. A previous change added NULL checks and cleanup for allocation failures in sma1307_setting_loaded(). However, the cleanup for mode_set entries is wrong. Those entries are allocated with devm_kzalloc(), so they are device-managed resources and must not be freed with kfree(). Manually freeing them in the error path can lead to a double free when devres later releases the same memory. Drop the manual kfree() loop and let devres handle the cleanup.

ASoC: codecs: wcd934x: fix typo in dt parsing

2026-04-02T11:23:17+00:00

commit cfb385a8dc88d86a805a5682eaa68f59fa5c0ec3 upstream. Looks like we ended up with a typo during device tree data parsing as part of 4f16b6351bbff ("ASoC: codecs: wcd: add common helper for wcd codecs") patch. This will result in not parsing the device tree data and results in zero mic bias values. Fix this by calling wcd_dt_parse_micbias_info instead of wcd_dt_parse_mbhc_data.

ASoC: adau1372: Fix clock leak on PLL lock failure

2026-04-02T11:23:15+00:00

[ Upstream commit bfe6a264effcb6fe99ad7ceaf9e8c7439fc9555b ] adau1372_enable_pll() was a void function that logged a dev_err() on PLL lock timeout but did not propagate the error. As a result, adau1372_set_power() would continue with adau1372->enabled set to true despite the PLL being unlocked, and the mclk left enabled with no corresponding disable on the error path. Convert adau1372_enable_pll() to return int, using -ETIMEDOUT on lock timeout and propagating regmap errors directly. In adau1372_set_power(), check the return value and unwind in reverse order: restore regcache to cache-only mode, reassert GPIO power-down, and disable the clock before returning the error.

ASoC: adau1372: Fix unchecked clk_prepare_enable() return value

2026-04-02T11:23:15+00:00

[ Upstream commit 326fe8104a4020d30080d37ac8b6b43893cdebca ] adau1372_set_power() calls clk_prepare_enable() but discards the return value. If the clock enable fails, the driver proceeds to access registers on unpowered hardware, potentially causing silent corruption. Make adau1372_set_power() return int and propagate the error from clk_prepare_enable(). Update adau1372_set_bias_level() to return the error directly for the STANDBY and OFF cases.

ASoC: cs35l56: Only patch ASP registers if the DAI is part of a DAIlink

2026-04-02T11:22:59+00:00

[ Upstream commit 9351cf3fd92dc1349bb75f2f7f7324607dcf596f ] Move the ASP register patches to a separate struct and apply this from the ASP DAI probe() function so that the registers are only patched if the DAI is part of a DAI link. Some systems use the ASP as a special-purpose interconnect and on these systems the ASP registers are configured by a third party (the firmware, the BIOS, or another device using the amp's secondary host control interface). If the machine driver does not hook up the ASP DAI then the ASP registers must be omitted from the patch to prevent overwriting the third party configuration. If the machine driver includes the ASP DAI in a DAI link, this implies that the machine driver and higher components (such as alsa-ucm) are taking ownership of the ASP. In this case the ASP registers are patched to known defaults and the machine driver should configure the ASP.
