From 33e5ee780e37bcf494013e2497580b00b7676507 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 18 Jan 2019 00:14:25 +0100 Subject: [PATCH] vfio/pci: Cleanup license mess 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.
