iommu: Check dev->iommu in dev_iommu_priv_get() before dereferencing it (2021-02-02 15:57:23 +0100)
----------------------------------------------------------------
IOMMU Fix for Linux v5.11-rc6
- Fix a possible NULL-ptr dereference in dev_iommu_priv_get()
which is too easy to accidentially trigger from IOMMU drivers.
In the current case the AMD IOMMU driver triggered it on some
machines in the IO-page-fault path, so fix it once and for
all.
