ide: make ide_unregister() take 'ide_hwif_t *' as an argument (take 2)
* 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(). v2: * Fixup ide_unregister() documentation.
