From: Markus Elfring <elfring@users.sourceforge.net> Date: Fri, 20 Jan 2017 16:30:18 +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 "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
