From a827977ac31cb5d1f4720efede9bbbf241789993 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 3 Jan 2015 17:06:04 +0100 Subject: [PATCH] ALSA: emu10k1: Delete an unnecessary check before the function call "kfree" The kfree() 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.
