From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Wed, 21 Sep 2016 12:23:46 +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.
