commit 277867ade8262583f4280cadbe90e0031a3706a7 upstream.
of_find_compatible_node() is calling of_node_put() on its first argument
thus leading to an unbalanced of_node_get/put() issue if the node has not
been retained before that.
Instead of passing the root node, pass NULL, which does exactly the same:
iterate over all DT nodes, starting from the root node.

Reported-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
Fixes: 3d61467f9bab ("irqchip: atmel-aic: Implement RTC irq fixup")
