From c6e9aefbf9db818d60818aa5540d78c1da289aae Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Wed, 9 Oct 2019 16:27:30 -0500 Subject: [PATCH] PCI/ATS: Remove unused PRI and PASID stubs The following functions are only used by amd_iommu.c and intel-iommu.c (when CONFIG_INTEL_IOMMU_SVM is enabled). CONFIG_PCI_PRI and CONFIG_PCI_PASID are always defined in those cases, so there's no need for the stubs. pci_enable_pri() pci_disable_pri() pci_reset_pri() pci_prg_resp_pasid_required() pci_enable_pasid() pci_disable_pasid() Remove the unused stubs.
