From: Jordan Crouse Date: Thu, 4 Jun 2020 14:39:04 -0600 Subject: iommu/arm-smmu: Mark qcom_smmu_client_of_match as possibly unused Git-commit: a082121b55bac125f7d09d78de00607ea75a6903 Patch-mainline: v5.8-rc6 References: bsc#1175713 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.
