Subject: [PATCH v2] iommu/arm-smmu: Mark qcom_smmu_client_of_match as possibly unused
Date: Thu, 4 Jun 2020 14:39:04 -0600 [thread overview]
Message-ID: <20200604203905.31964-1-jcrouse@codeaurora.org> (raw)
When CONFIG_OF=n of_match_device() gets pre-processed out of existence
leaving qcom-smmu_client_of_match unused. Mark it as possibly unused to
keep the compiler from warning in that case.
Fixes: 0e764a01015d ("iommu/arm-smmu: Allow client devices to select direct mapping")
Reported-by: kbuild test robot <lkp@intel.com>
Acked-by: Will Deacon <will@kernel.org>
Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org>
