[PATCH] PCI: Unhide the SMBus on the Compaq Evo D510

[Jean Delvare <khali@linux-fr.org>]

One more machine with a hidden Intel SMBus. Unhiding it reveals a SMSC
EMC6D100 hardware monitoring chip. I have checked that this machine
has no ACPI magic touching the SMBus nor the hardware monitoring chip,
so this should be safe.
