Subject: [PATCH v2 3/6] ALSA: hda/cs8409: Fix Full Scale Volume setting for all variants
From: Stefan Binding <sbinding@...nsource.cirrus.com>
All current variants (Bullseye/Warlock/Cyborg) should be using
reduced volume (-6dB) for better speaker protection.
Refactor to make more explicit the meaning and setting of
Full Scale Volume setting to avoid future confusion.
