That means GPL-2.0-only ? Please change this into GPL-2.0-or-later instead 
if possible, since according our main "LICENSE" file:

"As of July 2013, contributions under version 2 of the GNU General Public 
License (and no later version) are only accepted for the following files or 
directories: bsd-user/, linux-user/, hw/vfio/, hw/xen/xen_pt*"

While you're at it, I'd also appreciate a SPDX-License-Identifier line here.

  Thanks,
