From 753246840d012ae34ea80a1d40bc1546c62fb957 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Sat, 27 Aug 2016 16:19:49 +0000 Subject: [PATCH] drivers/perf: arm_pmu: Fix leak in error path 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().
