From: Takashi Iwai tiwai@suse.de Date: Wed, 10 Jan 2018 10:53:18 +0100 Subject: ALSA: hda - Apply the existing quirk to iMac 14,1
From: Takashi Iwai tiwai@suse.de
commit 031f335cda879450095873003abb03ae8ed3b74a upstream.
iMac 14,1 requires the same quirk as iMac 12,2, using GPIO 2 and 3 for headphone and speaker output amps. Add the codec SSID quirk entry (106b:0600) accordingly.
