From: Markus Elfring <elfring@users.sourceforge.net> Date: Wed, 19 Apr 2017 20:15:21 +0200 Multiplications for the size determination of memory allocations indicated that array data structures should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software.
