Subject[06/43] intel-iommu: Fix get_domain_for_dev() error path
2.6.33-longterm review patch.  If anyone has any objections, please let us know.


From: Alex Williamson <>

commit 2fe9723df8e45fd247782adea244a5e653c30bf4 upstream.

If we run out of domain_ids and fail iommu_attach_domain(), we
fall into domain_exit() without having setup enough of the
domain structure for this to do anything useful. In fact, it
typically runs off into the weeds walking the bogus domain->devices
list. Just free the domain.
