[PATCH 01/21] ACPI-video: Use kmalloc_array() in acpi_video_get_levels()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Mon, 5 Sep 2016 11:33:30 +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.
