[ Upstream commit 02298b7bae12936ca313975b02e7f98b06670d37 ]
of_irq_find_parent() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.
Fixes: cd844b0715ce ("irqchip/ti-sci-intr: Add support for Interrupt Router driver")
