Hello Geert.
Simplify rswitch_get_port_node() by using the for_each_available_child_of_node() helper instead of manually ignoring unavailable child nodes, and leaking a reference.
FYI, I have a patch in my queue that replaces this code with traversing child nodes (via for_each_available_child_of_node()) and only creating devices for ports actually defined in the device tree.
