Subject[PATCH 3.18 06/10] irqchip/atmel-aic: Fix unbalanced of_node_put() in aic_common_irq_fixup()
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Boris Brezillon <boris.brezillon@free-electrons.com>

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.
