The email is definitely better than the comment in the code.

I'm not concerned about the revision.  I'm concerned about the vendor 
(Generic*) and device name (STORAGE DEVICE*).  Why are the *'s needed? 
(Again, a PR would help track this kind of conversation as shown in 
previous PRs about quirks.  Submitters often match way too much.)

That would be nice, especially since some of the requested info is 
missing (dmesg, usbdevs -v).  However, if you cited a email in the 
commit msg (maybe SMTP Message-ID) such that we could find it in the 
future, that would probably be enough.  I'm not trying to create a 
bureaucracy, just make sure we don't lose information like we used to on 
why a quirk was added in the first place.
