[Qemu-devel] [PULL 1/1] virtio-gpu: fix memory leak in virtio_gpu_resource_create_2d

[Gerd Hoffmann]

From: Li Qiang <address@hidden>

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.
