    Tejun made it all very class based so you have inheriting operations
    structures thus in pata_via.c find

    static struct ata_port_operations via_port_ops = {
    .inherits = &ata_bmdma_port_ops,

    and change it to

    static struct ata_port_operations via_port_ops = {
    .inherits = &ata_bmdma32_port_ops,
