From: Markus Elfring <elfring@users.sourceforge.net> Date: Sat, 3 Sep 2016 17:10:20 +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.
