Subject: [PATCH] perf/smmuv3: Remove the leftover put_cpu() in error path
Date: Tue, 10 Dec 2019 18:46:24 +0800 [thread overview]
Message-ID: <1575974784-55046-1-git-send-email-guohanjun@huawei.com> (raw)
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.
