It got as far as staging with a good deal of complaint. I am not sure it
would have gotten further unfixed (with my serial/tty maintainers hat
on ;)). That however was about firmware - so a lot less tightly coupled.

Ultimately - ask a lawyer, ultimately this is a question about works and
copyright boundaries. If the hardware has only some specific proprietary
app then it sounds to me like it's not a general kernel interface so
probably isn't a good interface anyway, let alone what the code may do.
