Honestly after a second glance, I disagree. Literally a few lines before we do:

refnode = software_node_fwnode(ref->node);

We know very well what refnode is here and why we should use fwnode
API. If anything, the previous use of direct property routines was
unusual. A comment would be redundant as the code is self-describing,
what do you even want me to write there?
