Subject: [PATCH 3.19.y-ckt 062/155] ASoC: tas2552: Correct the Speaker Driver Playback Volume (PGA_GAIN)

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Ujfalusi <peter.ujfalusi@...com>

commit dd6ae3bcfe0fa9cf1bdb6f952c617f2070c57b37 upstream.

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.
