ALSA: hda: cs35l56: Fix system name string leaks

2026-05-25T07:22:23+00:00

cs35l56_hda_read_acpi() gets an allocated ACPI _SUB string from
acpi_get_subsystem_id(). On success, that string is used to create the
firmware system name.

Several error paths after the _SUB lookup can return without releasing
the allocated string. This includes speaker ID lookup errors other than
-ENOENT, and errors after a firmware system name has been allocated.

Use scoped cleanup for the temporary _SUB string and make
cs35l56->system_name device-managed. This releases the temporary _SUB
string on every error path and lets devres release the firmware system
name on probe failure and device removal.

ALSA: hda/cs35l56: Drop malformed default N from Kconfig

2026-05-15T07:08:04+00:00

First of all, it has to be 'default n' (small letter n), otherwise
it looks for CONFIG_N which is absent and in case of appearance
will enable something unrelated. Second and most important is that
'n' *is* the default 'default' already. Hence just drop malformed
line.

ALSA: hda: cs35l41: Put ACPI device on missing physical node

2026-05-07T14:31:25+00:00

acpi_dev_get_first_match_dev() returns a refcounted ACPI device and
callers must balance it with acpi_dev_put().

cs35l41_hda_read_acpi() stores the returned ACPI device in
cs35l41->dacpi. That reference is normally released by the later
probe cleanup or the remove path, but the NULL-check on
physdev exits before either of those paths can run.

Drop the lookup reference before returning -ENODEV.

ALSA: hda: cs35l56: Put ACPI device after setting companion

2026-05-07T14:31:25+00:00

acpi_dev_get_first_match_dev() returns a refcounted ACPI device and
callers are expected to balance it with acpi_dev_put().

When no companion is already attached, cs35l56_hda_read_acpi() looks
up an ACPI device and sets it with ACPI_COMPANION_SET(), but leaves
the lookup reference held.

ACPI_COMPANION_SET() does not take ownership of that reference, so
drop it with acpi_dev_put() after attaching the companion.

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()

2026-04-29T05:50:16+00:00

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: cs35l56: Propagate ASP TX source control errors

2026-04-27T11:48:41+00:00

cs35l56_hda_mixer_get() ignores regmap_read() and
cs35l56_hda_mixer_put() ignores regmap_update_bits_check().

This makes the ASP TX source controls report success when a regmap
access fails. The write path returns no change instead of an error,
and the read path continues after a failed read instead of aborting
the control callback.

Propagate the regmap errors, matching the posture and volume controls
in this driver.

In the SPI driver probe, the chip ID must be set to TAS2781. Without this
initialization, calibration data fails to load correctly, causing audio
abnormalities on some devices.
And update the register bulk read API to handle the distinct requirements
of SPI and I2C devices.

Merge tag 'asoc-v7.1' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2026-04-13T16:09:48+00:00

ASoC: Updates for v7.1

There's one new core feature here but mostly this has been a fairly
quiet release, we've got a few new drivers and one core feature that's
likely to be relatively rarely used but the bulk of the work this time
around has been on quality.

 - Support for bus keepers, this will be used by the Apple device
   support.
 - Enhancements to the SDCA support, incuding retaskable jacks.
 - Unwinding of the pcm_new()/pcm_free() cleanups from Morimoto-san.
 - Test improvements for the Cirrus Logic drivers.
 - Large sets of fixes for the NXP, nVidia and Qualcomm drivers.
 - Support for AMD RPL DMICs, Cirrus Logic CS42L43 and CS47L47, nVidia
   machines with CPCAP and WM8962.

ALSA: hda: cs35l41: Fix boost type for HP Dragonfly 13.5 inch G4

2026-03-30T16:24:57+00:00

The HP Dragonfly 13.5 inch G4 (SSID 103C8B63) has _DSD properties in
ACPI firmware with valid reset-gpios and cs-gpios for the four CS35L41
amplifiers on SPI.

However, the _DSD specifies cirrus,boost-type as Internal (0), while
the hardware requires External Boost. With Internal Boost configured,
the amplifiers trigger "Amp short error" when audio is played at
moderate-to-high volume, eventually shutting down entirely.

Add a configuration table entry to override the boost type to
External, similar to the existing workaround for 103C89C6. All GPIO
indices are set to -1 since the _DSD provides valid reset-gpios and
cs-gpios.

Confirmed on BIOS V90 01.11.00 (January 2026), the latest available.
