From 42d772101274492ca15258ea346e6ebbc2bc9bd0 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 21 Nov 2014 19:05:50 +0100 Subject: [PATCH] ALSA: es1688_lib: Deletion of an unnecessary check before the function call "release_and_free_resource" The release_and_free_resource() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
