The first issue is simply that most callers of of_irq_parse_one() and of_irq_parse_raw() don't call of_node_put() on the returned device node when they no longer need it. The second issue is a double get() happening in of_irq_parse_one() when parsing the "interrupts-extended" properties. WARNING: I tried to be careful when modifying the callers of of_irq_parse_one()/of_irq_parse_raw() but haven't test-build all the changes.
