From 096a8f835e7d19f0402386353586d285566eee06 Mon Sep 17 00:00:00 2001 From: Vishal Thanki Date: Fri, 11 May 2018 14:33:37 +0200 Subject: ASoC: davinci-mcasp: Only disable inactive serializer As a side effect of the following commit, the active TX serializer may get disabled which may result in distorted audio output. ASoC: davinci-mcasp: Add support for multichannel playback (2952b27e2e463b28d5c0f04000f96b968137ca42) For example, if a 4 channel I2S playback with two TX serializers is activated. Later on, if a recording of 2 channels, with only 1 RX serializer is started, which will also disable one of the TX serializer because max_active_serializers is only calculated for RX (recording) stream. This patch fixes this issue.
