From 6d13f62d931ba638e54ba56f3a7dd3080ffb485a Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Thu, 20 Oct 2016 12:26:16 +0200 Subject: [PATCH] ASoC: Intel: Skylake: Always acquire runtime pm ref on unload skl_probe() releases a runtime pm ref unconditionally wheras skl_remove() acquires one only if the device is wakeup capable. Thus if the device is not wakeup capable, unloading and reloading the module will result in the refcount being decreased below 0. Fix it.
