The fact what include/linux/license.h:license_is_gpl_compatible includes
"Dual MIT/GPL" as an option seems to suggest that it is enough of a thing
to be validly used as the contents of a MODULE_LICENSE() thing.

It's also inÂhttps://opensource.org/licenses/MITÂ;, the fact that it might
be confused for other licenses used by MIT notwithstanding.

FWIWÂhttps://en.wikipedia.org/wiki/MIT_LicenseÂseems to think that the
wording most commonly called the "MIT License" might be the "Expat
license", rather than the "X11 License" which is similar but different.
