[alsa-devel] [PATCH 6/13] ASoC: Intel: Delete an unnecessary check before the function call "sst_dma_free"

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sat, 3 Jan 2015 19:03:55 +0100

The sst_dma_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.
