This series attempts to fix refcounting issues related to of_irq_parse_one()
and of_irq_parse_raw().
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.
Jean-Jacques Hiblot (3):
of: irq: make callers of of_irq_parse_raw() release the device node
of: irq: make callers of of_irq_parse_one() release the device node
of: irq: release the node after looking up for "interrupts-extended"
