Subject: [PATCH] ipmi: Delete an unnecessary check before the function call
 "cleanup_one_si"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 27 Jun 2015 18:12:14 +0200

The cleanup_one_si() 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.
