ASoC: tas2552: Correct the Speaker Driver Playback Volume (PGA_GAIN) (dd6ae3bc) · Commits · 戴 / test

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. Signed-off-by:
