Re: RFC: WMI Enhancements

[Christoph Hellwig]

With Andy's conversion of WMI to the driver model the GUIDs should
be our device ids.  Which means WMI can support the dynamic device
ID model, where you can echo a id to sysfs to bind an id - that way
people could add the GUIDs on demand to the pass through driver if
they need them even with the whitelist approach.
