Merge tag 'iommu-fixes-v5.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fix from Joerg Roedel:
"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"
* tag 'iommu-fixes-v5.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu:
iommu: Check dev->iommu in dev_iommu_priv_get() before dereferencing it
