[PATCH 10/13] ALSA: sb: Delete an unnecessary check before the function call "snd_emux_free"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 3 Jan 2015 21:02:32 +0100

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.
