[PATCH] Input-rmi_bus: Delete an unnecessary check before the function call "of_node_put"

From: Markus Elfring <redacted>
Date: Sun, 24 Jul 2016 07:37:23 +0200

The of_node_put() 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.
