[PATCH 4/4] ide-pmac: move ide_find_port() call to pmac_ide_setup_device() (take 2)

From: Bartlomiej Zolnierkiewicz
Date: Mon Jun 16 2008 - 15:24:55 EST


Move ide_find_port() call to pmac_ide_setup_device().

While at it:

- fix return value (s/-ENODEV/-ENOENT/)

- add DRV_NAME define and use it to set name field of pmac_port_info

- use ide_find_port_slot() instead of ide_find_port()

- remove superfluous error message (ide_find_port_slot() takes care of it)

- drop IDE interface number from driver banner message (but include bus type)

v2:
* Build fix (thanks to Stephen Rothwell for noticing the issue).
