Subject: [PATCH 2/2] IB/usnic: Use kcalloc() in usnic_vnic_alloc_res_chunk()
Date: Thu, 6 Apr 2017 22:10:47 +0200	[thread overview]
Message-ID: <5d9ef1cc-44c5-b5a3-7ffd-3d94c517f129@users.sourceforge.net> (raw)
In-Reply-To: <f0a030a8-2a03-f531-57d8-39c2aeae28a4@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 6 Apr 2017 21:45:33 +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.
