Re: [PATCH] tipc: Add SPDX id lines to source files

[Tung Quang Nguyen]

I referred to https://opensource.org/license/bsd-3-clause:
The first line "Copyright <YEAR> <COPYRIGHT HOLDER>" does not seem look like what describe in current files:
"* Copyright (c) 2004-2005, 2010-2011, Wind River Systems
  * Copyright (c) 2020-2021, Red Hat Inc
 * All rights reserved.
"
Further more, GPL is mentioned in the paragraph makes me think that it is for GPL-2.0 license only.
I might be wrong or miss some history of current headers.
