The recently added nvlink2 VFIO driver introduced a license conflict in two
files. In both cases the SPDX license identifier is:
SPDX-License-Identifier: GPL-2.0+
but the files contain also the following license boiler plate text:
* This program is free software; you can redistribute it and/or modify
* it under the terms of the GNU General Public License version 2 as
* published by the Free Software Foundation
The latter is GPL-2.9-only and not GPL-2.0=.
Looking deeper. The nvlink source file is derived from vfio_pci_igd.c which
is also licensed under GPL-2.0-only and it can be assumed that the file was
copied and modified. As the original file is licensed GPL-2.0-only it's not
possible to relicense derivative work to GPL-2.0-or-later.
Fix the SPDX identifier and remove the boiler plate as it is redundant.
