Use consistent address conversions in the driver: - virt_to_phys(): For all virtual to physical address conversion, convert __pa users as we don’t need to rely on it type casting. - phys_to_virt(): For all physical to virtual address conversion, similarly, convert __va users. That changes nothing at all. However, it will be useful when compiling this file for the KVM hypervisor as it can cleanly replace virt_to_phys/phys_to_virt Signed-off-by: Mostafa Saleh <smostafa@google.com> Reviewed-by: Jason Gunthorpe <jgg@nvidia.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
