From 34067c56fa177d3582695da8e3e162ef78cd0371 Mon Sep 17 00:00:00 2001 From: Jon Derrick Date: Tue, 21 Jan 2020 06:37:46 -0700 Subject: x86/PCI: Expose VMD's pci_dev in struct pci_sysdata Expose VMD's pci_dev pointer in struct pci_sysdata. This will be used indirectly by intel-iommu.c to find the correct domain.
