[PULL 12/31] hw/i386/amd_iommu: Move capab_offset from AMDVIState to AMDVIPCIState
Posted by Michael S. Tsirkin 2 years, 7 months ago
From: Philippe Mathieu-Daudé <philmd@linaro.org>

The 'PCI capability offset' is a *PCI* notion. Since AMDVIPCIState
inherits PCIDevice and hold PCI-related fields, move capab_offset
from AMDVIState to AMDVIPCIState.
