Not everything in libc is expected to set errno on failure - in fact
most functions don't (though they may alter it) and shouldn't.
errno is (mostly) intended for sys calls - the values defined for it are
chosen with that (mostly) in mind - there are a few other functions that have
no other reasonable way to indicate errors, and so also use errno, but those
are decidedly in the minority.
devname() is in neither set, having it return errors through errno would be
