Subject: [PATCH 3/5] IB/qib: Use kcalloc() in qib_alloc_devdata()
Date: Wed, 5 Apr 2017 15:53:47 +0200	[thread overview]
Message-ID: <9bcddc18-197c-0784-bb25-8ac6446d8fb6@users.sourceforge.net> (raw)
In-Reply-To: <c16b18ac-287f-5faf-b79a-c86e2adfa22c@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 5 Apr 2017 14:15:45 +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.
