Subject[PATCH 1/2] IB/usnic: Use kcalloc() in alloc_res_chunk_list()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 6 Apr 2017 20:32:39 +0200

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.
