You meant "GPL v2".

"GPLv2" is not one of the idents that pass license_is_gpl_compatible().
Loading a module with that ident should trigger a warning and taint the
kernel. See linux/module.h (or linux/license.h) for acceptable idents.

This is a bit of a gotcha. A patch that would have helped here was
posted in https://lkml.org/lkml/2015/4/7/824 . I don't know why that
patch didn't make it into checkpatch.pl. Bjorn?

Thanks,


Paul Bolle
