From: Markus Elfring <redacted> Date: Thu, 25 Aug 2016 17:45:23 +0200 Multiplications for the size determination of memory allocations indicated that array data structures should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software.
