    Subject[PATCH 5.10 013/126] ASoC: es8316: Simplify adc_pga_gain_tlv table
    Date
    From: Hans de Goede <hdegoede@redhat.com>

    [ Upstream commit bb18c678754ce1514100fb4c0bf6113b5af36c48 ]

    Most steps in this table are steps of 3dB (300 centi-dB), so we can
    simplify the table.

    This not only reduces the amount of space it takes inside the kernel,
    this also makes alsa-lib's mixer code actually accept the table, where
    as before this change alsa-lib saw the "ADC PGA Gain" control as a
    control without a dB scale.
