PCI: vmd: IRQ domain assignment to sub devices

Make sure VMD assigns proper IRQ domain to the child devices during device enumeration. DMAR errors were observed when interrupt remapping is enabled by intel_iommu because of the fact that VMD child devices are on different IRQ domain than all other PCI devices. Nirmal Patel (2): PCI: vmd: Assign VMD IRQ domain before enumeration PCI: vmd: Revert 2565e5b69c44 ("PCI: vmd: Do not disable MSI-X remapping if interrupt remapping is enabled by IOMMU.") drivers/pci/controller/vmd.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-)
