[PATCH 1/4] clk/Renesas-MSTP: Use kmalloc_array() in cpg_mstp_clocks_init()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 14 Sep 2016 21:10:47 +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.
