I'm not aware of any, frankly speaking.

If there are any, those tools should be able to handle the -ENODEV
they get. Now, if this gets changed this way, the read would succeed
but they'll have to parse the returned value and see that it is not an
integer.

So I don't know either.

But my gut feeling says to stay concervative and not touch this code -
we don't know what uses it and how much we would break by "fixing" it.
The current situation is not that big of a deal IMVHO and I'd be willing
to accept the small inconcistency versus possibly breaking userspace.

Thanks.
