ALSA: hda/tas2781: Fix incorrect bit update for non-book-zero or book 0 pages >1

2026-04-29T05:51:17Z

In TAS2781 SPI mode, when accessing non-book-zero or page numbers greater than 1 in book 0, an additional byte must be read. The first byte in such cases is a dummy byte and should be ignored.

ALSA: hda: cs35l56: Fix uninitialized value in cs35l56_hda_read_acpi()

2026-04-29T05:50:16Z

Eliminate the uninitialized 'nval' in cs35l56_hda_read_acpi() if a system-specific quirk overrides processing of the dev-index property. The value is now stored in a new 'num_amps' member of struct cs35l56_hda so that the quirk handler can set the value. The quirk for the Lenovo Yoga Book 9i GenX replaces the values from the dev-index property with hardcoded indexes. So cs35l56_hda_read_acpi() would then skip reading the property. But this left the 'nval' local variable uninitialized when it is later passed to cirrus_scodec_get_speaker_id().

ALSA: hda/conexant: Fix missing error check for jack detection

2026-04-29T05:49:44Z

In cx_probe(), the return value of snd_hda_jack_detect_enable_callback() is ignored. This function returns a pointer, and if it fails (e.g., due to memory allocation failure), it returns an error pointer which must be checked using IS_ERR(). If the registration fails, the driver continues to probe, but the jack detection callback will not be registered. This can lead to a kernel crash later when the driver attempts to handle jack events or accesses the uninitialized structure. Check the return value using IS_ERR() and propagate the error via PTR_ERR() to the probe caller.

ALSA: hda: Avoid WARN_ON() for HDMI chmap slot checks

2026-04-29T05:49:09Z

At parsing the channel mapping for HDMI, the current code may spew WARN_ON() unnecessarily for the case where only invalid (zero) channel maps are given from the hardware. Drop WARN_ON() and reorganize the code a bit for avoiding the hdmi_slot over the array size.

ASoC: spacemit: adjust FIFO trigger threshold to half FIFO size

2026-04-29T02:41:32Z

Set both TX and RX FIFO trigger thresholds (TFT/RFT) to 0xF (half of the 32-entry FIFO) instead of 5. This provides better DMA efficiency by allowing more data to accumulate before triggering a DMA request, reducing the number of DMA transactions needed.

ASoC: spacemit: move hw constraints from hw_params to startup

2026-04-29T02:41:32Z

Hardware constraints should be applied in the startup callback rather than hw_params, as hw_params may be called too late for the constraints to take effect properly. Move the channel count and format constraints for I2S and DSP_A/DSP_B modes into a new startup callback. This also tightens the I2S mode channel constraint from 1-2 to exactly 2, matching the actual hardware behavior.

ASoC: codecs: ab8500: Fix casting of private data

2026-04-29T00:47:39Z

ab8500_filter_controls[i].private_value is initialized using .private_value = (unsigned long)&(struct filter_control) {.count = xcount, .min = xmin, .max = xmax} thus it's a pointer to a struct filter_control casted to unsigned long. So to get back that pointer .private_data must be cast back, not its address. Fixes: 679d7abdc754 ("ASoC: codecs: Add AB8500 codec-driver") Signed-off-by: Christian A.

ASoC: cs35l56: Fix illegal writes to OTP_MEM registers

2026-04-28T23:41:14Z

Mark the OTP_MEM registers as volatile so that regcache_sync() will not attempt to write to them. These registers hold a constant, and originally they were marked as readable non-volatile so that this value would be read into the regmap cache. The problem with this is regcache_sync() issues a write for any cached register that does not have a reg_default. Though these registers are constants and writing them in normal use cannot change OTP, it is illegal for the host to write to them.
