ASoC: amd: yc: Fix internal mic for HP board 8C30

[PATCH] ASoC: amd: yc: Fix internal mic for HP board 8C30

Posted by David 2 weeks, 5 days ago

The HP laptop with AMD Ryzen 5 7535HS and ACP 6.x coprocessor (PCI ID
1022:15e2, subsystem 103c:8c30) requires an entry in yc_acp_quirk_table[]
to enable the internal digital microphone (DMIC).

Without this quirk, acp6x_probe() returns -ENODEV and the internal
microphone remains undetected.

Add a DMI quirk matching vendor "HP" and board name "8C30" to enable
ACP DMIC support.
