[PATCH 1/6] GPU-DRM-GMA500: Use kmalloc_array() in mid_get_vbt_data_r10()

From: SF Markus Elfring <hidden>
Date: 2016-09-20 08:56:03
Also in: dri-devel, lkml
Subsystem: drm drivers, drm drivers and misc gpu patches, drm drivers for gma500 (poulsbo, moorestown and derivative chipsets), the rest · Maintainers: David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Patrik Jakobsson, Linus Torvalds

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.
