From 5988a363edb9eb9f31486ceb2cd10e8b45f05dda Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Tue, 31 May 2016 12:41:23 +0100 Subject: drivers/perf: arm_pmu: Avoid leaking pmu->irq_affinity on error pmu->irq_affinity will not be freed if an error occurred within arm_pmu_device_probe after of_pmu_irq_cfg has been called. Note that in the case of_pmu_irq_cfg is returning an error, pmu->irq_affinity will not be set, but it should be NULL as pmu was kzalloc'd. Therefore the result kfree(NULL) is benign.
