Subject: [ 74/78] ASoC: ak4642: fixup: mute needs +1 step

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

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

From: Kuninori Morimoto <kuninori.morimoto.gx@...esas.com>

commit 1f99e44cf059d2ed43c5a0724fa738b83800f725 upstream.

ak4642 out_tlv is +12.0dB to -115.0 dB, and it supports mute.
But current settings didn't care +1 step for mute.
This patch adds it
