Subject: ALSA: hda/realtek - Add headset mode support for Dell laptop

From: Kailang Yang <[email protected]>

commit ae104a21e52b1f9aab342cf6924405177b720069 upstream.

This platform was only one phone Jack.
Add dummy lineout verb to fix automute mode disable. This just the workaround.

[ More background information:
since the platform has only a headphone jack without speaker, the driver doesn't create the auto-mute control. Meanwhile we do update the headset mode via the automute hook in the driver, thus with this setup, the headset won't be updated any longer.

By adding a dummy line-out pin here, the auto-mute is added by the driver, and the headset update is triggered properly.

Note that this is different from the other ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, which has the real line-out pin, while this quirk adds a dummy line-out pin. -- tiwai ]
