[PATCH] ASoC: amd: yc: Add DMI quirk for MSI Alpha 17 C7VF

From: Zhang Heng

Date: Fri Oct 16 2026 - 08:40:53 EST


The DMIC does not work on the MSI Alpha 17 C7VF because the ACP6x
machine driver lacks a matching DMI quirk. Add the DMI entry so the
driver binds correctly and the DMIC is functional.
