Julien Grall 121323ae66 drivers/perf: arm_pmu: Fix reference count of a device_node in of_pmu_irq_cfg ... The only function called by of_pmu_irq_cfg that will increment the reference count on dn is of_parse_phandle. Each time we successfully parse a possible CPU from an interrupt-affinity property, we increment the refcount of that CPU node once via of_parse_handle. After validating the CPU is possible, we decrement the refcount once. Subsequently, we decrement the refcount again, either as part of an early break if we don't have a matching SPI, or as part of the end of the loop body. This will lead to decrementing twice the refcounnt. Remove the second pairs of call to of_node_put as nobody is using dn between the first and second call to of_node_put.
