Subject: [PATCH] NetCP: Deletion of unnecessary checks before two function
 calls

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 3 Feb 2015 20:12:25 +0100

The functions cpsw_ale_destroy() and of_dev_put() test whether their argument
is NULL and then return immediately. Thus the test around the call
is not needed.

This issue was detected by using the Coccinelle software.
