drm/virtio: Fix double free on probe failure

2021-07-19T07:44:39+00:00

[ Upstream commit cec7f1774605a5ef47c134af62afe7c75c30b0ee ] The virtio_gpu_init() will free vgdev and vgdev->vbufs on failure. But such failure will be caught by virtio_gpu_probe() and then virtio_gpu_release() will be called to do some cleanup which will free vgdev and vgdev->vbufs again. So let's set dev->dev_private to NULL to avoid double free.

If a response to virtio_gpu_cmd_get_capset_info takes longer than five seconds to return, the callback will access freed kernel memory in vg->capsets.
