[PATCH] convert IDE device drivers to driver-model
* add ide_bus_match() and export ide_bus_type * split ide_remove_driver_from_hwgroup() out of ide_unregister() * move device cleanup from ide_unregister() to drive_release_dev() * convert ide_driver_t->name to driver->name * convert ide_driver_t->{attach,cleanup} to driver->{probe,remove} * remove ide_driver_t->busy as ide_bus_type->subsys.rwsem protects against concurrent ->{probe,remove} calls * make ide_{un}register_driver() void as it cannot fail now * use driver_{un}register() directly, remove ide_{un}register_driver() * use device_register() instead of ata_attach(), remove ata_attach() * add proc_print_driver() and ide_drivers_show(), remove ide_drivers_op * fix ide_replace_subdriver() and move it to ide-proc.c * remove ide_driver_t->drives, ide_drives and drives_lock * remove ide_driver_t->drivers, drivers and drivers_lock * remove ide_drive_t->driver and DRIVER() macro Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@elka.pw.edu.pl>
