Since commit c40c1018 ("iommu/vt-d: Gracefully handle DMAR units
with no supported address widths") dmar.c needs struct iommu_device to
be defined. We need to unconditionally select IOMMU_API when DMAR_TABLE
is selected. 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’

Thanks!

How about making it symmetric with the registration code?

if (intel_iommu_enabled && !iommu->drhd->ignored)

Best regards,
