v2: change Spacing on Initializer, change Mailing List link
This patch had previously been suggested at
https://lore.kernel.org/netdev/1407426826-11335-2-git-send-email-dhollis@davehollis.com/

However, I found that the flag quirk is not necessary and I suspect
it has never worked (because it references ".flag" whereas the
identifying value is in ".data")

I have compiled this and tested successfully with two devices.
As it now only adds the USB Id it generates no extra maintenance
burden that's why I suggest it for inclusion.
