While at it remove redundant pci_get_slot() call as cy82c693_init_one()
already takes care of keeping the reference on the second port's PCI
device.

Please do not submit unrelated changes with a bug fix, and as IDE is
in long-term maintainence I would not accept a risky refinement like
this anyways.

Removed code is just bogus, we cannot fail in ->set_pio_mode method.

Please take a look at the code:
 
-	/* select primary or secondary channel */
-	if (hwif->index > 0) {  /* drive is on the secondary channel */
-		dev = pci_get_slot(dev->bus, dev->devfn+1);
-		if (!dev) {
-			printk(KERN_ERR "%s: tune_drive: "
-				"Cannot find secondary interface!\n",
-				drive->name);
-			return;
-		}
-	}

Please apply the patch, libata's pata_cypress doesn't support secondary
port currently and cy82c693 driver is the only way to use this hardware.

I've not found anyone using an Alpha 164SX in years so it's not been
possible to do the updates and test them. And no ... do not offer to send
me an Alpha, donate it to a museum.
