[alsa-devel] [PATCH] ASoC: rt5677: use more of the volume range from DACs

[Curtis Malainey]

From: Dylan Reid <dgreid at chromium.org>

The DACs volume can go over 0, both according to the data sheet and
real world testing.  The control can go up to +30dB.

This was tested by playing audio at full volume on a samus chromebook.
