[PATCH 1/1] ASoC: fsi: Deletion of unnecessary checks before the function call "clk_disable"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 2 Dec 2014 14:34:30 +0100

The clk_disable() 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.
