For a valid ID used in a patch submitted by an employee of the relevant
company this is a steep ask.  As far as I'm concerned it is definitely not
a requirement (unlike for non compliant IDs!) There is no reason why a
device might be public at this time. 

For a good upstream first company almost all IDs go into the kernel
'before' device announcement or sales.  I very much want to encourage
that not put potential barriers in the way.

So Victor, if you can provide the info Andy requested, then great but if not
feel free to say so. (+ the snippet is useful anyway and is unlikely
to contain anything confidential.)
