From 02c91ece4ee644fbe87933a870c660c0e8413d41 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Mon, 17 Apr 2017 08:09:07 +0200 Subject: net: mvpp2: Use kmalloc_array() in mvpp2_txq_init() * 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. * Replace the specification of a data structure by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
