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.

Thanks. Joerg -- can you pick this one up, please? I don't have any other SMMU fixes pending at the moment. Cheers, Will _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
