[PATCH] irqchip/alpine-msi: Fix refcount leak in alpine_msix_init_domains
From: Miaoqian Lin <hidden>

arm/annapurna labs alpine architecture, irqchip drivers, the rest · Maintainers:
Antoine Tenart, Thomas Gleixner, Linus Torvalds
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: e6b78f2c3e14 ("irqchip: Add the Alpine MSIX interrupt controller")
