From c2ac3aec474da0455df79c4a182f19687bc98d1d Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Thu, 9 Feb 2023 12:27:59 +0000 Subject: [PATCH] ASoC: qcom: q6apm-lpass-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.
