From 677cc6443b28508bb1a34d4d0d6a9b9a20179369 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 21 Nov 2007 18:29:06 +0100 Subject: [PATCH] PCI: Unhide the SMBus on the HP xw4100 Unhide the SMBus on the HP xw4100. This gives access to a hardware monitoring chip (ADT7463) and to the memory module SPD EEPROMs. I checked that ACPI wasn't accessing the SMBus, so it should be safe.
