Precise and non-ambiguous license information is important. The recently
added morus header files have a SPDX license identifier, which is nice, but
at the same time they have a contradictionary license boiler plate text.

  SPDX-License-Identifier: GPL-2.0

versus 

  * This program is free software; you can redistribute it and/or modify it
  * under the terms of the GNU General Public License as published by the Free
  * Software Foundation; either version 2 of the License, or (at your option)
  * any later version

Oh well.

As the other morus related files are licensed under the GPL v2 or later,
it's assumed that the boiler plate code is correct, but the SPDX license
identifier is wrong.

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.

Shouldn't this be: /* SPDX-License-Identifier: GPL-2.0+ */ ?

At least this is the form documented in Documentation/process/license-rules.rst:

" License identifiers for licenses like [L]GPL with the 'or later' option
   are constructed by using a "+" for indicating the 'or later' option.::

      // SPDX-License-Identifier: GPL-2.0+"

Either works, please see LICENSES/preferred/GPL-2.0

Personally, I think we should stick with the "+" version as that is the
much more prevalent use in the kernel at the moment, but it's Thomas's
call, not mine.

thanks,

Thanks, I must have copy-pasted the bits from somewhere and didn't
notice the discrepancy...

(feel free to keep the ack also if you decide to switch to the "GPL-2.0+" form)
