From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Fri, 7 Oct 2016 22:07:27 +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 "kmalloc_array". 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.
