Subject: [patch 9/9] vfio/pci: Cleanup license mess
Date: Fri, 18 Jan 2019 00:14:25 +0100	[thread overview]
Message-ID: <20190117231501.654003681@linutronix.de> (raw)
In-Reply-To: 20190117231416.111952141@linutronix.de

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.

P.S.: This patch is part of a larger cleanup, but independent of other
      patches and is intended to be picked up by the maintainer directly.
