[PATCH] sysfs: Delete an unnecessary check before the function call "kernfs_get"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 4 Nov 2015 20:44:50 +0100

The kernfs_get() 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.
