Subject: [PATCH 3/4] hwmon-nct6775: Use devm_kcalloc() in
 nct6775_create_attr_group()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 27 Apr 2017 10:35:36 +0200

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "devm_kcalloc".

This issue was detected by using the Coccinelle software.
