From: Markus Elfring <elfring@users.sourceforge.net> Date: Thu, 26 Jan 2017 19:47:38 +0100 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.
