Subject: [PATCH 03/25] net: mvneta: Use kmalloc_array() in mvneta_txq_init()
Date: Mon, 17 Apr 2017 17:13:08 +0200	[thread overview]
Message-ID: <d3e0290e-78fe-9134-4e1f-6f09d82c2a56@users.sourceforge.net> (raw)
In-Reply-To: <d6f26bba-c678-5b66-4f5d-85f56d895190@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 16 Apr 2017 22:11:22 +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 "kmalloc_array".

This issue was detected by using the Coccinelle software.
