Since commit c40aaaac ("iommu/vt-d: Gracefully handle DMAR units with no supported address widths") dmar.c needs struct iommu_device to be selected. We can drop this dependency by not dereferencing struct iommu_device if IOMMU_API is not selected and by reusing the information stored in iommu->drhd->ignored instead. This fixes the following build error when IOMMU_API is not selected: drivers/iommu/intel/dmar.c: In function ‘free_iommu’: drivers/iommu/intel/dmar.c:1139:41: error: ‘struct iommu_device’ has no member named ‘ops’ 1139 | if (intel_iommu_enabled && iommu->iommu.ops) { ^ Fixes: c40aaaac ("iommu/vt-d: Gracefully handle DMAR units with no supported address widths") Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com> Acked-by: Lu Baolu <baolu.lu@linux.intel.com> Acked-by: David Woodhouse <dwmw@amazon.co.uk> Link: https://lore.kernel.org/r/20201013073055.11262-1-brgl@bgdev.plSigned-off-by: Joerg Roedel <jroedel@suse.de>
