AMD IOMMU: don't remove protection domain from iommu_pd_list · 9e919012

Joerg Roedel authored Dec 10, 2008

Impact: save unneeded logic to add and remove domains to the list

The removal of a protection domain from the iommu_pd_list is not
necessary. Another benefit is that we save complexity because we don't
have to readd it later when the device no longer uses the domain.
