Subject: drivers/perf: arm_pmu: Fix leak in error path
From: Stefan Wahren <stefan.wahren@xxxxxxxx>
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().
