[PATCH] ASoC: amd: yc: Add DMI entry for HP Laptop 15-fc0xxx

From: Gilson Marquato Júnior via B4 Relay

Date: Sun Mar 29 2026 - 21:45:39 EST


From: Gilson Marquato Júnior <gilsonmandalogo@xxxxxxxxxxx>

The HP Laptop 15-fc0xxx (subsystem ID 0x103c8dc9) has an internal
DMIC connected to the AMD ACP6x audio coprocessor. Add a DMI quirk
entry so the internal microphone is properly detected on this model.

Tested on HP Laptop 15-fc0237ns with Fedora 43 (kernel 6.19.9).
