A few places use -ENOTSUPP when they should use -ENOSYS. In two cases both are used. This little series tidies this up.

I think we need to start this series with a doc update that makes it clear why this is correct and when it should be used. There's two instances of "ENOSYS" in doc/driver-model/ today and neither explains why this series is correct (which I'm sure it is). Thanks.
