Description
In the Linux kernel, the following vulnerability has been resolved:
irqchip/ti-sci: Fix refcount leak in ti_sci_intr_irq_domain_probe
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.
