[PATCH 1/4] hwmon-nct6683: Use devm_kcalloc() in nct6683_create_attr_group()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 27 Apr 2017 10:10:36 +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.
