Message-Id: <20080324185337.15320.23504.sendpatchset@localhost.localdomain>

Subject: [PATCH 3/5] ide: make ide_unregister() take 'ide_hwif_t *' as an argument
* Make ide_unregister() take 'ide_hwif_t *hwif' instead of 'unsigned int
index' (hwif->index) as an argument and update all users accordingly.
While at it:
* Remove unnecessary checks for hwif != NULL from ide-pnp.c::idepnp_remove()
and delkin_cb.c::delkin_cb_remove().
* Remove needless hwif->chipset assignment from scc_pata.c::scc_remove().
