You appear to have missed the continuation of that comment directly 
underneath which lists a subset of the devices covered by the quirks.

Say one of the machines turns out to need the quirk for two different 
reasons. How do we document that? Look, how about you add the comments 
and I'll do a patch that adds documentation to the existing entries? I'm 
not asking you to make up for other people's past mistakes, I'm asking 
you not to perpetuate them.

No, that's not what I'm saying. But I'm now going to a bar and drink 
instead of having to justify why *clearly documenting this code* is a 
worthwhile thing to do.
