From ecab76688a0785fbcddcd1ff638a3fc76db073aa Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sun, 18 Sep 2016 17:00:52 +0200 Subject: [PATCH] drm/amdgpu: Use kmalloc_array() in amdgpu_debugfs_gca_config_read() 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.
