[PATCH 07/12] ide: init hwif->{io_ports,irq} explicitly in legacy VLB host drivers

From: Bartlomiej Zolnierkiewicz
Date: Sat Feb 16 2008 - 11:27:01 EST


Do explicit port setup in legacy VLB host drivers instead of depending
on init_ide_data(). This way hwif->io_ports[] and hwif->irq are always
correctly set regardless of CONFIG_PCI / CONFIG_BLK_DEV_IDEPCI.

[ No need to care about "idex=noprobe" parameter for these drivers
as they need to be explicitly enabled with "probe" parameter. ]
