Not sure why this still remains there. But it seems not alone.

$ git grep iommu_sva_unbind_gpasid
Documentation/userspace-api/iommu.rst:  int 
iommu_sva_unbind_gpasid(struct iommu_domain *domain,
include/linux/iommu.h:extern int iommu_sva_unbind_gpasid(struct 
iommu_domain *domain,

I believe the document should also be removed.
