[alsa-devel] [PATCH 07/10] ASoC: twl6040: No need to change delay during HS ramp

[Peter Ujfalusi]

The Headset 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 0x0 raw at
one end of the range, and not in the middle.
