Subject: [PATCH 3.8 087/133] ASoC: cs42l51: Fix SOC_DOUBLE_R_SX_TLV shift values for ADC, PCM, and Analog kcontrols

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

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

From: Brian Austin <brian.austin@...rus.com>

commit 7272e051157ccd5871b5d939548d0ba5a94a2965 upstream.

The shift values for the ADC,PCM, and Analog kcontrols were wrong causing wrong values for the SOC_DOUBLE_R_SX_TLV macros
Fixed the TLV for aout_tlv to show -102dB correctly

Fixes: 1d99f2436d (ASoC: core: Rework SOC_DOUBLE_R_SX_TLV add SOC_SINGLE_SX_TLV)
