Subject: drivers/perf: arm_pmu: Fix leak in error path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=753246840d012ae34ea80a1d40bc1546c62fb957;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

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().
