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!
