I'm pretty sure we can kill it. I had the plan to rip it out during this merge
window
along with other broken UML stuff but I was too late to ask on the UML
mailinglist
if someone is using it (which I really doubt).
So, let's kill it with v4.2.
Or we move it into drivers/staging and hope that someone else is fixing it for
us?
...just kidding. ;-)
Thanks,
