    Subject[PATCH 6/13] ASoC: Intel: Delete an unnecessary check before the function call "sst_dma_free"
    From: Markus Elfring <elfring@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.
