From 2355fd50b39e767c952217aa5b6a93b7cc4e2273 Mon Sep 17 00:00:00 2001 From: Bard Liao Date: Wed, 24 Jun 2026 17:37:54 +0800 Subject: [PATCH] soundwire: dmi-quirks: add a global ghost list Not like other ghost devices, the 0x000000D010010500 ADR doesn't belong to any codec. We should disable it in all devices.
