20090625 regression in AcpiGetDevices

[Moore, Robert]

We've just discovered a regression in 20090625 that seriously affects the AcpiGetDevices interface. The _HID and _CID strings are no longer matched properly and will confuse any bus-scanning code that uses the interface.

The ACPICA bugzilla is below, it contains a patch for the problem.

Apologies for any inconvenience.
Bob

Fix for AcpiGetDevices ID matching

This is a regression introduced with the _HID/_CID/_UID string changes for
version 20090625.

In AcpiGetDevices, the _HID and _CID strings are not matched properly. This will break any bus scanning code that depends on this function.

Patch is attached.
