Bug Description
== SRU Justification ==
[Impact]
There is only one audio jack on this machine (codename: zuma-p), so
there is only one output device (headphone), then the driver will not generate
auto-mute control on this machine, without auto-mute, the headset-mode
initialization routine will not be called, as a result, all audio devices
can't work (output and input). To fix it, add a dummy lineout on this
machine, then there are two output devices (headphone + lineout), the
driver will create auto-mute control on this machine finally.
Due to the patch conflicts, I prepared two patches, one is for artful+oem,
the other is for bionic.
[Test Case]
plug the headset and play or record the sound on this machine, both playing
and recording work well.
[Fix]
one commit from mainline kernel.
[Regression Potential]
very low, since this patch only applies to the specific Dell machine Precision 3930.

ALSA: hda/realtek - Add headset mode support for Dell laptop
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 FIXUP_DELL_ AIO_LINEOUT_ VERB, which has the real line-out pin,
ALC274_
while this quirk adds a dummy line-out pin. -- tiwai ]
