I think:
- EBUSY is a better error return than EEXIST here/
- do the ENODEV case first, because claiming something is busy when
you couldn't have used it anyway is kind of stupid)
but yeah, this looks like the right thing. Let's make sure there
aren't any annoying error messages etc printed out as a result of
this, though.
