Subject[PATCH 1/9] IB/IPoIB: Use kcalloc() in two functions
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 7 Apr 2017 17:43:51 +0200

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.
