linux-toradex.git/drivers/perf, branch v5.5-rc3 Linux kernel for Apalis and Colibri modules perf/smmuv3: Remove the leftover put_cpu() in error path 2019-12-18T16:15:36+00:00 Hanjun Guo guohanjun@huawei.com 2019-12-11T06:43:06+00:00 8ae4bcf4821c18a8fbfa0b2c1df26c1085e9d923 In smmu_pmu_probe(), there is put_cpu() in the error path, which is wrong because we use raw_smp_processor_id() to get the cpu ID, not get_cpu(), remove it. While we are at it, kill 'out_cpuhp_err' altogether and just return err if we fail to add the hotplug instance.

In smmu_pmu_probe(), there is put_cpu() in the error path,
which is wrong because we use raw_smp_processor_id() to
get the cpu ID, not get_cpu(), remove it.

While we are at it, kill 'out_cpuhp_err' altogether and
just return err if we fail to add the hotplug instance.
