Which is a good idea :-)

Yep.

When intentionally putting the 'missing license' in the header files we just
oriented to other header files, where a more detailed license was only
provided in the C files.

Btw. when reworking the license information in the header files I would
suggest to take the version which was checked by our lawyer - which is e.g. in
linux/net/can/raw.c

It has parts of BSD and alternatively refers to GPLv2. And it's not too long.

Does this fit the Debian requirements?

Tnx & brest regards,
