From: Kailang Yang kailang@realtek.com

commit 9226665159f0367ad08bc7d5dd194aeadb90316f upstream.

Dell AIO had LineOut jack. Add LineOut verb into this patch.

[ Additional notes: the ALC274 codec seems requiring the fixed pin / DAC connections for HP / line-out pins for enabling EQ for speakers; i.e. the HP / LO pins expect to be connected with NID 0x03 while keeping the speaker with NID 0x02. However, by adding a new line-out pin, the auto-parser assigns the NID 0x02 for HP/LO pins as primary outputs. As an easy workaround, we provide the preferred_pairs[] to map forcibly for these pins. -- tiwai ]
