Thanks for this change. See my nit-pick below.

In cases like this, I would rather see something like

	struct fwnode_handle *fwnode = dev_fwnode(dev);

just near to the respective of node extraction. This will help to reduce churn
when converting the rest of the code to use fwnode instead of of_node/np.

Other than that I appreciate the series!
