[alsa-devel] [PATCH 5/13] ALSA: emux: Delete an unnecessary check before the function call "snd_sf_free"

The snd_sf_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.
