+Subject: [PATCH 0215/2940] drm/amdgpu: remove redundant memset
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+kvmalloc_array uses __GFP_ZERO flag ensures that the returned address
+is zeroed already, memset it to zero again afterwards is unnecessary,
+and in this case buggy because we only clear the first entry.
