Subject: irqchip/atmel-aic: Fix unbalanced of_node_put() in aic_common_irq_fixup()
From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx>
commit 469bcef53c546bb792aa66303933272991b7831d upstream.
aic_common_irq_fixup() is calling twice of_node_put() on the same node
thus leading to an unbalanced refcount on the root node.
