Roberto Sassu b094fece38 drm/virtio: Ensure that objs is not NULL in virtio_gpu_array_put_free() ... commit 6b79f96f4a upstream. If virtio_gpu_object_shmem_init() fails (e.g. due to fault injection, as it happened in the bug report by syzbot), virtio_gpu_array_put_free() could be called with objs equal to NULL. Ensure that objs is not NULL in virtio_gpu_array_put_free(), or otherwise return from the function.
