IANAL, but I think this file is also licensed under GPL-2.0 from
the doc below (and as you state by MODULE_LICENSE()), so you
may want to follow other similar files throughout this series.

  $ grep -rnI SPDX net | grep GPL | grep BSD


Documentation/process/license-rules.rst

The license described in the COPYING file applies to the kernel source
as a whole, though individual source files can have a different license
which is required to be compatible with the GPL-2.0::

    GPL-1.0+  :  GNU General Public License v1.0 or later
    GPL-2.0+  :  GNU General Public License v2.0 or later
    LGPL-2.0  :  GNU Library General Public License v2 only
    LGPL-2.0+ :  GNU Library General Public License v2 or later
    LGPL-2.1  :  GNU Lesser General Public License v2.1 only
    LGPL-2.1+ :  GNU Lesser General Public License v2.1 or later

Aside from that, individual files can be provided under a dual license,
e.g. one of the compatible GPL variants and alternatively under a
permissive license like BSD, MIT etc
