In the Linux kernel, the following vulnerability has been resolved:
iommu: Fix NULL group->domain dereference in pci dev reset iommu done()
Local sashiko review pointed it out that group->domain could be NULL when
a default domain fails to allocate during the first probe, which can crash
at domain->ops->attach dev dereference in iommu attach device() invoked
by pci dev reset iommu done().
pci dev reset iommu prepare() is fine as an old domain pointer can be NULL.
Skip the re-attach in pci dev reset iommu done() to fix the bug.
