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

From: SF Markus Elfring
Date: Tue Dec 02 2014 - 08:42:03 EST

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.
