Subject: [PATCH 1/4] GPU-DRM-TILCDC: Use kmalloc_array() in kfree_table_init()
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 22 Sep 2016 09:05:14 +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.
