[PATCH] clk-kona-setup: Use kmalloc_array() in parent_process()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 14 Sep 2016 20:26:05 +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.
