From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Sun, 16 Apr 2017 21:23:19 +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 "devm_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.
