Subject[PATCH 3/3] thermal: int340x: Use kcalloc() in int340x_thermal_zone_add()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 10 Apr 2017 21:56:58 +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 "kcalloc".

This issue was detected by using the Coccinelle software.
