soundwire: dmi-quirks: Disable ghost Realtek on Asus GX651AX

6d49beec · Ian Luites <[email protected]> · 2026-08-31 08:25:47 +00:00

The Asus ROG Zephyrus Duo GX651AX exposes a Realtek RT722 device in
ACPI which does not exist in the physical hardware. The device remains
unattached while the CS42L43 and both CS35L56 devices attach
successfully.

This confuses the function topology machine driver into creating
duplicate DAI links named SDW3-Playback-SimpleJack, and the sof_sdw
probe fails with error -12. Add a model-specific quirk to remove the
ghost RT722 device.
