4.12-stable review patch. If anyone has any objections, please let me know. ------------------ 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.
