From 4b34fe156455d26ee6ed67b61539f136bf4e439c Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 2 Jun 2008 16:42:49 -0600 Subject: PNP: mark resources that conflict with PCI devices "disabled" Both the PNP/PCI conflict detection quirk and the PNP system driver must use the same mechanism to mark resources as disabled. I think it's best to keep the resource and to keep the type bit (IORESOURCE_MEM, etc), so that we match the list from firmware as closely as possible.

Trying to reserve them results in messages like this, which are ugly but harmless: system 00:08: iomem range 0x0-0x0 could not be reserved Future PNP patches will remove use of IORESOURCE_UNSET, but we still need it for now.
