ide: use 'drive->dn & 1' instead of drive->select.b.unit
* Call ide_port_init_devices() in ide_host_register() also if 'struct ide_port_info *d' is not available. * Init drive->dn in ide_port_init_devices() instead of ide_probe_port() so it is valid also in ->init_dev. * Pass device number to ide_dev_apply_params(). * Use 'drive->dn & 1' instead of drive->select.b.unit. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
