Joerg Roedel 95f89e0906 vfio/type1: Initialize resv_msi_base ... After enabling CONFIG_IOMMU_DMA on X86 a new warning appears when compiling vfio: drivers/vfio/vfio_iommu_type1.c: In function ‘vfio_iommu_type1_attach_group’: drivers/vfio/vfio_iommu_type1.c:1827:7: warning: ‘resv_msi_base’ may be used uninitialized in this function [-Wmaybe-uninitialized] ret = iommu_get_msi_cookie(domain->domain, resv_msi_base); ~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The warning is a false positive, because the call to iommu_get_msi_cookie() only happens when vfio_iommu_has_sw_msi() returned true. And that only happens when it also set resv_msi_base. But initialize the variable anyway to get rid of the warning.
