[PATCH] ASoC: mmp-sspa: clear transmit phase bit for non-stereo formats

From: Kyle Russell
Date: Fri Nov 06 2020 - 09:59:31 EST


The transmit phase register value is never cleared during hw params.
So once hw params sets this bit to handle a two channel format, it
remains configured for dual-phase, which is not desirable for mono
playback.
