From decc27b01d584c985c231e73d3b493de6ec07af8 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Tue, 7 Oct 2014 13:41:23 +0200 Subject: [PATCH] ASoC: core: fix use after free in snd_soc_remove_platform() Coverity spotted an use-after-free condition in snd_soc_remove_platform(). Fix this by moving snd_soc_component_cleanup() after the debug print statement which uses the component's string.
