[PATCH 1/1] ALSA: echoaudio: Deletion of a check before release_and_free_resource()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 2 Dec 2014 18:34:45 +0100

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.
