* Add ide_device_add() helper and convert host drivers to use it instead of open-coded variants. * Make ide_pci_setup_ports() and do_ide_setup_pci_device() take 'u8 *idx' argument instead of 'ata_index_t *index'. * Remove no longer needed ata_index_t. * Unexport probe_hwif_init() and make it static. * Unexport ide_proc_register_port(). There should be no functionality changes caused by this patch (sgiioc4.c: ide_proc_register_port() requires hwif->present to be set and it won't be set if probe_hwif_init() fails).
