I don't think this is the right fix. of_find_node_by_name() should
generally not be used by drivers in the first place as it searches the
entire tree and can end up matching an entirely unrelated node.

I haven't looked at the device-tree binding in question, but you
probably want to use something like of_get_child_by_name() instead.
