[alsa-devel] [PATCH 15/22] ASoC: tas2552: Correct the Speaker Driver Playback Volume (PGA_GAIN)

[Peter Ujfalusi]

The last parameter for DECLARE_TLV_DB_SCALE() is to tell if the gain will
be muted or not when it is set to raw 0. IN this case it is not muted.
The PGA_GAIN is in 0-4 bits in the register. Fix the offset in the
SOC_SINGLE_TLV() for this.
