From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Wed, 24 Aug 2016 17:45:51 +0200 A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus reuse the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software.
