[alsa-devel] [PATCH 08/10] ASoC: twl6040: No need to change delay during HF ramp

[Peter Ujfalusi]

The Handsfree gain have 2dB steps all the way, so there is no
reason to have different delays as we approaching to the
end of the scale.
The comment was also wrong, since we have 0dB at 0x3 raw, at 16 the gain
is -26dB.
