If KFD_SUPPORT_IOMMU_V2 is not set, gcc warns:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_device.c:121:37: warning: ‘raven_device_info’ defined but not used [-Wunused-const-variable=] static const struct kfd_device_info raven_device_info = { ^~~~~~~~~~~~~~~~~
As Huang Rui suggested, Raven already has the fallback path, so it should be out of IOMMU v2 flag.
