From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Wed, 5 Apr 2017 09:43:54 +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 "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of a data structure by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
