| |
From: Markus Elfring <elfring@users.sourceforge.net> Date: Thu, 5 Feb 2015 14:10:21 +0100
The functions clk_enable() and clk_disable() test whether their argument is NULL and then return immediately. Thus the test around the calls is not needed.
This issue was detected by using the Coccinelle software.
