4.7-stable review patch. If anyone has any objections, please let me know.
------------------ From: Stefan Wahren <[email protected]> commit 753246840d012ae34ea80a1d40bc1546c62fb957 upstream. In case of a IRQ type mismatch in of_pmu_irq_cfg() the device node for interrupt affinity isn't freed. So fix this issue by calling of_node_put().
