Since commit c40aaaac1018 ("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) {

address widths")

Do you want me to resend it again with a changed title or can you fix
it up when applying? Or should someone else pick it up?
I suppose Joerg will pick this up. I guess you don't need to resend it
unless Joerg asks you to do.
Best regards,
baolu
