ASoC: mediatek: mt6358: save output volume for mixer controls
Output volume settings from mixer controls would be lost. Imagine that "Headphone Volume" has set to -10dB via amixer: - in mtk_hp_enable() - hp_store_gain() saves the volume setting -10dB from regmap_read() to ana_gain[AUDIO_ANALOG_VOLUME_HPOUTL] - headset_volume_ramp() ramps up from -10dB to -10dB - in mtk_hp_disable() - headset_volume_ramp() ramps down from -10dB to -40dB Next time in mtk_hp_enable(), hp_store_gain() would save -40dB but not -10dB. As a result, headset_volume_ramp() would ramp from -10dB to -40dB (which is mute). Signed-off-by: Tzung-Bi Shih <tzungbi@google.com> Signed-off-by: Mark Brown <broonie@kernel.org>
