From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Tue, 4 Oct 2016 10:10:52 +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. * Replace the specification of data types by pointer dereferences to make the corresponding size determination a bit safer according to the Linux coding style convention.
