Should this be GPL-2.0+? The MODULE_LICENSE specifies that the module is
"GPL" which in kernel land means GPLv2+. Or we should change the module
license to strict "GPLv2"?

Also, why do we use C++ -style comments for this?

Greg, do you have any plans on dropping MODULE_LICENSE() altogether and
generating the appropriate string from SPDX markings in the source?
Doing this would prevent mismatches between license notices, SPDX tags
and MODULE_LCENSE() strings, which happen very often.
