From d643678b9a4e432a574b2ec601216afd720c69b6 Mon Sep 17 00:00:00 2001 From: Jeeja KP Date: Mon, 28 Mar 2016 22:11:30 +0530 Subject: [PATCH] ASoC: Intel: Skylake: Fix for unloading module only when it is loaded Module needs to be unloaded only when it is loaded successfully. To fix this, first correct the module state sequence and set module state to LOADED if module is loaded successfully. When unloading the module check if module state is not in UNINIT, then unload it.
