Subject: [PATCH 1/2] ARM-kernel: Delete an unnecessary check before the function
call "smp_set_ops"
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 25 Jun 2015 15:00:17 +0200
The smp_set_ops() 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.
