[PATCH 1/1] SPI-txx9: Deletion of an unnecessary check before the function call "clk_disable"

[SF Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 29 Nov 2014 18:34:20 +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.
