[PATCH 2/2] regulator: s2mps11: Use devm_kmalloc_array() in s2mps11_pmic_probe()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 14 Apr 2017 22:40:19 +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.
