[PATCH 0/2] ALSA: hda: aw88399: Add per-model firmware loading

[Marco Giunta]

The AW88399 HDA side codec driver currently requests firmware using
the same hardcoded generic filename ("aw88399_acf.bin") as the ASoC driver
it was derived from.
This requires users to manually extract the firmware from the
Windows driver, rename it with this model-independent name, and place
it in /lib/firmware, which is not sustainable for distribution packaging.

This series adds support for per-model firmware filenames based on the
ACPI subsystem ID (e.g. "awinic/aw88399_acf_17aa3938.bin"), making the
driver compatible with the linux-firmware repository's per-device naming
convention.
ACF firmware binaries for the currently supported Lenovo Legion models
have been submitted to the linux-firmware ML by AWINIC [1] (currently
pending review).

The series is as follows:

* Patch 1 adds a name parameter to the shared firmware request function
  so callers can specify the filename.

* Patch 2 uses the ACPI subsystem ID to construct model-specific firmware
  names in the HDA driver.

Note: since there are still some AW88399 patches either pending merge or
that have yet to cross the ASoC/HDA bridge (see the note in [2]), I based
this series on linux-next, meaning a rebase may be needed before merging.
Apologies for the extra noise; I'm sending the series now for review
as I'd rather not miss the 7.4 merge window.

Best regards,
Marco
