I just want to fill in that the former license text (removed in
51b751f112dcbb24b46051fe64c2ddbe8aa367ea) was:

- * The code contained herein is licensed under the GNU General Public
- * License. You may obtain a copy of the GNU General Public License
- * Version 2 or later at the following locations:

According to this, the SPDX-identifier is valid and the MODULE_LICENSE
should be fixed.
