[PATCH 10/14] GPU-DRM-OMAP: Use kmalloc_array() in omap_gem_attach_pages()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Wed, 21 Sep 2016 17:37:04 +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.
