[PATCH] i386:acpi: Remove _HID from the SMBus ACPI entry

[minyard]

From: Corey Minyard <address@hidden>

Per the ACPI spec (version 6.1, section 6.1.5 _HID) it is not required
on enumerated buses (like PCI in this case), _ADR is required (and is
already there).  And the _HID value is wrong.  Linux appears to ignore
the _HID entry, but it confuses Windows.
