vers/gpu/drm/nouveau/nvkm/subdev/ltc/gp10b.c:37:9: error: implicit declaration of function dev_iommu_fwspec_get; did you mean iommu_fwspec_free? [-Werror=implicit-function-declaration]
  spec = dev_iommu_fwspec_get(device->dev);
         ^~~~~~~~~~~~~~~~~~~~
         iommu_fwspec_free
drivers/gpu/drm/nouveau/nvkm/subdev/ltc/gp10b.c:37:7: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
  spec = dev_iommu_fwspec_get(device->dev);
       ^
drivers/gpu/drm/nouveau/nvkm/subdev/ltc/gp10b.c:39:17: error: struct iommu_fwspec has no member named ids
   u32 sid = spec->ids[0] & 0xffff;

Seletc IOMMU_API under config DRM_NOUVEAU to fix this.
