ALSA: hda/cs35l41: Fix firmware load work teardown
cs35l41_hda creates ALSA controls whose private data points at the
cs35l41_hda object. The firmware load control can also queue
fw_load_work.
Those controls are not removed on component unbind, and device remove
only cancels fw_load_work through cs35l41_remove_dsp(). That helper is
skipped when halo_initialized is false. With firmware_autostart
disabled, a firmware load can be requested before the DSP has been
initialized. If the component or device is removed before the queued
work runs, the worker can run after teardown and dereference driver
state that is no longer valid.
Track the created controls and remove them on unbind so no new control
callback can reach the driver data or queue more work. Then cancel
fw_load_work to drain any request that was already queued. Also cancel
the work unconditionally during device remove before runtime PM teardown.

ALSA: hda/cs35l56: Drop malformed default N from Kconfig
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
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/tas2781: Fix sound abnormal issue on some SPI device
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.

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