From e910ea663dae49381ac244f486a65b625949f9fe Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Fri, 10 Jun 2022 15:48:18 +0100 Subject: [PATCH] ASoC: qdsp6: q6apm-dai: unprepare stream if its already prepared prepare callback can be called multiple times, so unprepare the stream if its already prepared. Without this DSP is not happy to setting the params on a already prepared graph.
