From: Jordan Crouse Date: Thu, 4 Jun 2020 20:39:04 +0000 (-0600) Subject: iommu/arm-smmu: Mark qcom_smmu_client_of_match as possibly unused X-Git-Tag: microblaze-v5.10~329^2 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=a082121b55bac125f7d09d78de00607ea75a6903;p=linux-2.6-microblaze.git iommu/arm-smmu: Mark qcom_smmu_client_of_match as possibly unused 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.
