ASoC: codecs: lpass-tx-macro: Fix enum kcontrol accesses

2026-08-27T12:29:05+00:00

[ Upstream commit 1ba381759e45d5d0442452cfa5c42e836191a568 ] The "DEC0 MODE" to "DEC7 MODE" controls are enumerated, but tx_macro_dec_mode_get() and tx_macro_dec_mode_put() access their value through ucontrol->value.integer.value[0] (a long) instead of ucontrol->value.enumerated.item[0] (an unsigned int). This same pattern was fixed in the sibling drivers by commit bcfe5f76cc40 ("ASoC: codecs: rx-macro: fix accessing array out of bounds for enum type") and commit 0ea5eff7c606 ("ASoC: codecs: va-macro: fix accessing array out of bounds for enum type"), but tx-macro was missed. On 64-bit kernels built with CONFIG_SND_CTL_DEBUG, the elem value sanity check catches the 4 bytes written past the enumerated item and every read of these controls fails with -EINVAL: snd-sm8250 sound: control 2:0:0:DEC0 MODE:0: access overflow Fixes: c39667ddcfc5 ("ASoC: codecs: lpass-tx-macro: add support for lpass tx macro") Assisted-by: Claude:claude-fable-5 Cc: stable@vger.kernel.org Signed-off-by: Dawid Wróbel Reviewed-by: Srinivas Kandagatla Link: https://patch.msgid.link/20260730-worktree-lpass-tx-macro-enum-fix-v2-1-6d091c736116@dawidwrobel.com Signed-off-by: Mark Brown [ kept `snd_soc_kcontrol_component()` context line instead of upstream's renamed `snd_kcontrol_chip()` ] Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

ALSA: dummy: Check card index validity at probe

2026-08-27T12:29:01+00:00

commit 02442d5fe8ee365a084b055d4fa81a0c1abfc3fd upstream. snd_dummy_probe() blindly trusts that the given devptr->id value is within the proper card index range. It's OK for the devices the driver itself creates at the module probe time, but if the device is bound manually via sysfs interface, this could be -1 as "none", and this leads to OOB access for index[] and other parameters. Add a sanity check for the card index and warn/correct it if it's a value out of the range.

ASoC: xilinx: formatter_pcm: pass aud_drv_data to irq handlers

2026-08-23T12:18:36+00:00

[ Upstream commit f12afefb7b01f94d6d66d397f323a9914edbf70e ] The irq handlers take a struct device pointer and call dev_get_drvdata() to obtain the driver data. However, the driver data is only set at the end of probe, after devm_request_irq(), so an interrupt taken in between causes the handlers to pass a NULL pointer to readl() and crash. Pass the private data directly as the devm_request_irq() argument instead of the device pointer, matching what the handlers expect.

ASoC: fsl_sai: Fix spurious BCLK on resume by clearing BYP

2026-08-23T12:18:31+00:00

[ Upstream commit d091132889c1378dd0944a72f86eae3e4da1e4fa ] When the BCLK divider ratio is 1:1, fsl_sai_set_bclk() enables bypass mode by setting BYP, but never clears the bit. The BYP=1 value remains in the regcache, and is restored by regcache_sync() on the next runtime resume. Since BYP=1 combined with BCD=1 immediately outputs the ungated MCLK as BCLK without waiting for BCE/TE/RE to be enabled, the clock is driven prematurely before the stream is fully configured, causing noise on some codecs. Fix this by clearing BYP and BCI in fsl_sai_hw_free() taking into account sync mode and the opposite stream's state, so that the regcache holds BYP=0 before runtime suspend and regcache_sync() on resume will not restore bypass mode prematurely.

ALSA: hda: codecs: hdmi: disable keep-alive before audio format change

2026-08-23T12:18:30+00:00

[ Upstream commit a3d6d3cedfe87bbd5a677d52b22ac20d28e59cf8 ] When a keep-alive (KAE) silent stream is active on an Intel HDMI/DP codec, opening a real PCM stream reprograms the converter format and the audio infoframe in snd_hda_hdmi_generic_pcm_prepare(). Part of that reprogramming - the converter channel count and the channel mapping in snd_hda_hdmi_setup_audio_infoframe() - is not safe to do while a keep-alive stream is active. This is most visible when switching to a multichannel PCM configuration, where the active channel count actually changes. In that case the newly opened PCM stream plays no sound. Add an optional hdmi_ops .prepare hook, called at the start of the PCM prepare sequence (before the format and infoframe are touched), and implement it for HSW+ to release keep-alive. Keep-alive is then re-enabled as before once the new stream has been set up, in the setup_stream op.

ASoC: mediatek: mt8192: Check runtime resume during probe

2026-08-23T12:18:22+00:00

[ Upstream commit e24d5dde56a50946020b134fa8448869093db76a ] The MT8192 AFE probe enables runtime PM temporarily while reinitializing the regmap cache from hardware, but it uses pm_runtime_get_sync() without checking the return value. If runtime resume fails, probe keeps going without the device necessarily being accessible, and pm_runtime_get_sync() may leave the PM usage count incremented. The regmap_reinit_cache() failure path also returns before dropping the temporary PM reference and before clearing pm_runtime_bypass_reg_ctl. Use pm_runtime_resume_and_get() so resume failures do not leak a usage count, and clear the temporary bypass flag after dropping the probe PM reference on all regmap_reinit_cache() outcomes.

ASoC: mediatek: Use common mtk_afe_pcm_platform with common probe cb

2026-08-23T12:18:22+00:00

[ Upstream commit 1d2a6b3b5189b6c3e51f29e050aa9b2337b774e8 ] Since the mtk-afe-platform-driver generic mtk_afe_pcm_platform now has a common .probe() callback, there is no reason to keep duplicating this function over and over in the SoC specific AFE-PCM drivers: switch over to register with the common bits instead. Note that MT8186 was left out of this because it is registering some extra sinegen controls in the AFE-PCM probe callback and needs extra cleanups to be able to use the common bits.
