  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.
