[PATCH] PowerPC-PCI: Delete unnecessary checks before the function call "kfree"

From: SF Markus Elfring <hidden>
Date: 2015-02-03 13:01:24
Also in: kernel-janitors, lkml
Subsystem: cell broadband engine architecture, linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Linus Torvalds

From: Markus Elfring <redacted>
Date: Tue, 3 Feb 2015 13:55:53 +0100

The kfree() 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.
