[PATCH 26/26] IB/ocrdma: Adjust further ten checks for null pointers

2017-03-08 Thread SF Markus Elfring 
From: Markus Elfring 
Date: Wed, 8 Mar 2017 12:50:14 +0100
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The script “checkpatch.pl“ pointed information out like the following.

Comparison to NULL could be written !…

Thus fix affected source code places.
