From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Fri, 14 Apr 2017 18:48:15 +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. * Delete the local variable "nregs" which became unnecessary with this refactoring.
