[PATCH 17/26] ALSA: hda: cs35l41: Support Speaker ID for laptops
Vitaly Rodionov
vitalyr at opensource.cirrus.com
Wed Apr 27 17:07:11 CEST 2022
From: Stefan Binding <sbinding at opensource.cirrus.com>
Some Laptops use a number of gpios to define which vendor is
used for a particular laptop.
Different coefficient files are used for different vendors.
