From 260eb73aa252d0cbdfe11523d5def9d6d00625d4 Mon Sep 17 00:00:00 2001 From: Dharageswari R Date: Fri, 3 Jun 2016 18:29:38 +0530 Subject: [PATCH] ASoC: Intel: Skylake: Avoid freeing up of unallocated memory/mcps When DSP pipe/module is not initialized successfully, memory/mcps is not allocated. So check the pipe/module state to avoid freeing up of unallocated memory/mcps. And allocate resources when pipe/ module is initialized successfully.
