Ok, so I read that as if it should be v2 *only* and not v2-or-later.
I.e. the reverse of the original patch. But since these things can
be sensitive, I'd like confirmation that this new patch is what is
correct...

Note that MODULE_LICENSE("GPL") means GPL v2 *or later* (GPL v1 is
not on the table), while MODULE_LICENSE("GPL v2") means GPL v2 *only*.
See include/linux/module.h for details.

Cheers,
Peter
