You forgot this one :)

I would do the following instead
struct fwnode_handle *(*get_next_child_node)(struct fwnode_handle *fwnode,
struct fwnode_handle *child);
struct fwnode_handle *(*get_named_child_node)(struct fwnode_handle *fwnode,
const char *name);
Yes, it is over 80 chars but it is more readable this way.
Just saying :) I'll leave this up to you.
