[PATCH 1/5] drm/amdgpu: Use kmalloc_array() in amdgpu_debugfs_gca_config_read()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sun, 18 Sep 2016 17:00:52 +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.
