[PATCH] ASoC: amd: yc: Add DMI quirk for HP OmniBook 3 Laptop 16-by0xxx

From: Gianluca Balboni

Date: Sat Oct 31 2026 - 06:21:55 EST


The HP OmniBook 3 Laptop 16-by0xxx (board ID 8EE3) has an internal DMIC
connected to the AMD ACP6x audio coprocessor. The BIOS does not set the
AcpDmicConnected _DSD property or the _WOV method, and the board is missing
from yc_acp_quirk_table[], so acp6x_probe() returns -ENODEV and no DMIC
capture device is registered.

Add a DMI quirk entry for this model to enable ACP DMIC support.
