Hello maintainers, There is no "SPDX-License-Identifier: GPL-2.0" in arch/alpha/kernel/smc37c669.c and the following copyright is found. " Copyright (C) 1997 by Digital Equipment Corporation, Maynard, Massachusetts. All rights reserved. " Does this conflict with GPLv2? Anything else we need to know when using this as opensource software? Thanks, Zhe
