vfio/nvlink: Add missing SPAPR_TCE_IOMMU depends
Compiling the nvlink stuff relies on the SPAPR_TCE_IOMMU otherwise there are compile errors: drivers/vfio/pci/vfio_pci_nvlink2.c:101:10: error: implicit declaration of function 'mm_iommu_put' [-Werror,-Wimplicit-function-declaration] ret = mm_iommu_put(data->mm, data->mem); As PPC only defines these functions when the config is set. Previously this wasn't a problem by chance as SPAPR_TCE_IOMMU was the only IOMMU that could have satisfied IOMMU_API on POWERNV. Fixes: 179209fa1270 ("vfio: IOMMU_API should be selected") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Message-Id: <0-v1-83dba9768fc3+419-vfio_nvlink2_kconfig_jgg@nvidia.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
