[PATCH 0/3] of: irq: Fixes refcount issues with of_irq_parse_one()/of_irq_parse_raw()

[Jean-Jacques Hiblot]

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"
