Subject: drivers/perf: arm_pmu: Fix leak in error path

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().

Fixes fa8ad7889d83 ("arm: perf: factor arm_pmu core out to drivers")
