Summary: Guitar Hero World Tour crashes after dinput
                    GetProperty
           Product: Wine

         Component: directx-dinput

        ReportedBy: [e-mail]

After I set a fake paging file in regedit, game will crash after this line:
warn:dinput:IDirectInputDevice2AImpl_GetProperty Unknown property <guid-0x0018>

The problem is, we return DI_OK instead of an error code.
It can be fixed with this:
diff --git a/dlls/dinput/device.c b/dlls/dinput/device.c
