Buffers were not returned to vb2 when the instance was already in\n   error state, triggering warnings in the vb2 core because buffer\n   completion was skipped.\n\n2. If a session failed early (e.g. unsupported configuration), the\n   instance transitioned to IRIS_INST_ERROR. When userspace attempted\n   to stop streaming for cleanup, stop_streaming was skipped due to the\n   added check, preventing proper teardown and leaving the firmware\n   in an inconsistent state."
