Subject: [PATCH] driver/perf: Remove ARM_SMMU_V3_PMU dependency on ARM_SMMU_V3
Date: Mon, 1 Feb 2021 18:24:02 +0800 [thread overview]
Message-ID: <1612175042-56866-1-git-send-email-john.garry@huawei.com> (raw)
The ARM_SMMU_V3_PMU dependency on ARM_SMMU_V3_PMU was added with the idea
that a SMMUv3 PMCG would only exist on a system with an associated SMMUv3.
However it is not the job of Kconfig to make these sorts of decisions (even
if it were true), so remove the dependency.
