From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Thu, 9 Feb 2017 16:06:12 +0100 * Multiplications for the size determination of memory allocations indicated that array data structures should be processed. Thus reuse 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.
