Subject: [PATCH 2/3] ALSA: hda/realtek: Enable headset mic of Acer C20-820 with ALC269VC
Date:   Fri,  3 Jul 2020 15:05:14 +0800

The Acer Aspire C20-820 AIO's audio (1025:1065) with ALC269VC can't
detect the headset microphone until ALC269VC_FIXUP_ACER_HEADSET_MIC
quirk maps the NID 0x18 as the headset mic pin.
