From a6a867552a36e647cbd35aceae24754c9bcd3661 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Thu, 3 Sep 2026 11:27:43 +0100 Subject: [PATCH] soundwire: dmi-quirks: Disable ghost Realtek on Lenovo Pro 9 The Lenovo Pro 9 also has a Realtek device in the ACPI that doesn't exist in the physical hardware. This confuses the machine driver into attempting to create DAI links for the device. Add a quirk to remove this device.
