[PATCH v2 2/4] drm/virtio: fix object leak in virtio_gpu_resource_create_ioctl()

[Junrui Luo via B4 Relay]

From: Junrui Luo <moonafterrain@xxxxxxxxxxx>

virtio_gpu_resource_create_ioctl() calls drm_gem_object_release() on the
drm_gem_handle_create() error path instead of dropping the reference it
owns, so obj->funcs->free() never runs and the virtio_gpu_object, its
pages and sg table, the resource id and the host-side resource are
leaked.

Use drm_gem_object_put() instead.

Fixes: 62fb7a5e1096 ("virtio-gpu: add 3d/virgl support")
