Sorry for the late reply, I was out.
Yeah, I am pretty sure it is the same. Heikki proposed a fix that I am going to try.
Also, I think I am going to send out a new test case for this that can live with the fwnode, software_node stuff. It would be nice if the printf test wasn't the only thing testing this stuff.
Thanks!
