[PATCH v4 0/1] PCI/ATS: Mandate checking pci_ats_supported() before pci_prepare_ats()

[Pranjal Shrivastava <praan@google.com>]

Hi Bjorn,

This single-patch submission represents the final core enforcement for the 
PCIe ATS robustness hardening effort.

This work was split into two parallel driver-specific consolidation series:
 1. Intel & ARM [1]
 2. AMD [2]

All the prerequisite driver refactors from both series have now been 
merged into the IOMMU tree by Joerg, with the latest merge commit [3].

As the driver-side safety checks are now fully in place, Joerg 
requested [4] that this final, PCI core patch be submitted through the
PCIe tree. Hence, I'm sending this as a standalone patch rebased on the
pci tree (for-next branch).

Thanks,
Praan
