From a39cf72ceb406e152c4682c0b635a96f1439c5ed Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Thu, 17 Nov 2005 16:44:57 -0500 Subject: [PARISC] Make superio.c initialize before any driver needs it Convert superio_init to use PCI_FIXUP_FINAL as ohci_pci being called before superio_probe really makes a mess. superio_init will then fail to register irq 20 (the "SuperIO" irq) and BUG() because ohci_pci has stolen it before superio_fixup_irq can be moved USB to irq 1.
