Yah, ENOTTY is correct. However, there are some circumstances where
EOPNOTSUPP is appropriate, though. Consider the case of a driver which
fits into a subsystem which exports a feature, but the driver does not
support that particular feature... that would be a case where
EOPNOTSUPP would be appropriate.
that said, I have not looked at this diff, and don't know if there are
any such cases in it :-)
