Subject: [PATCH 5/9] 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.
