Indeed, there isn't much left from the uapi header. I see to options.

The first is to accept this situation and mark nvme-cli as GPL-2.0-only
or second we reimplement the necessary parts under GPL-2.0-or-later.

Most of the content is just function declarations and the implementation
is licensed under GPL-2.0-or-later. Do we really have to consider these
declarations as GPL-2.0-only? So this could be moved to a new header
file which is licensed under GPL-2.0-or-later, I suppose.

The rest of the file could be reimplemented fairly simple. What you think?
