[PATCH] ASoC: tlv320aic31xx: do not declare support for mono DAI

From: Nikita Yushchenko
Date: Tue Sep 27 2016 - 04:30:15 EST


This hardware supports only 2-channel DAI, even mono ADC digital output
has two channels with the same data.

Having min_channels=1 results in broken playback of mono files in setups
where CPU DAI supports mono.
