This patch adds support for the ESS Sabre HiFi DAC found on some System76 and Clevo laptops. These devices can be identified using the Clevo subvendor id, and the Realtek ALC898 codec vendor ID. When a connection is detected on the ESS DAC, identified by GPIO pin 2 being set low, the 0x1b pin VREF should be set to 80%. Otherwise, it should be set to HIZ. Testing has been performed on the current System76 line of laptops, with and without DACs, no regressions have been found.

Please give your sign off. Otherwise it can't be merged at all.

Looking at the changes, the changes themselves look almost good. But the patch isn't applicable as is because of spacing or line break. Please fix your MUA setup or use an attachment if it really doesn't work.

Also, last but not least, try to run checkpatch.pl and fix the reported issues there.

thanks,

Takashi
