From c7165ba4e131a7e6b774f254bad735983ee19482 Mon Sep 17 00:00:00 2001 From: Li Qiang <liqiang6-s@360.cn> Date: Sun, 18 Sep 2016 19:07:11 -0700 Subject: [PATCH] virtio-gpu: fix memory leak in virtio_gpu_resource_create_2d MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In virtio gpu resource create dispatch, if the pixman format is zero it doesn't free the resource object allocated previously. Thus leading a host memory leak issue. This patch avoid this.
