ide_reinit_drive() turned into ata_attach(). Said beast takes a drive, tries to feed it to high-level drivers and drops it on the ata_unused if nobody claims the sucker. IOW, that's what ide_register_module() used to do, but for a single drive. ideprobe_init() calls ata_attach() instead of putting on ata_unused. ide_register_module() eliminated. Some of the callers do not need it anymore, some (ide_replace_subdriver()) actually want ata_attach(drive). ide_scan_devices() is gone. There were two remaining callers - in ide_register_module() and ide_unregister_module(). The former had been turned into "put driver on the list, empty ata_unused into temporary list and call ata_attach() on all drives there". The latter is "remove driver from the list, call ->cleanup() and ata_attach() for all drives" (->cleanup() gives the drive up, ata_attach() gives the remaining drivers a shot for that drive; if nobody claims it - it's put on ata_unused).
