From: Markus Elfring Date: Sat, 3 Jan 2015 20:02:32 +0000 (+0100) Subject: ALSA: sb: Delete an unnecessary check before the function call "snd_emux_free" X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b76c0e95ab0f535e210df588b8ac42dd75b31c75;p=openwrt%2Fstaging%2Fblogic.git ALSA: sb: Delete an unnecessary check before the function call "snd_emux_free" The snd_emux_free() 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.
