Erm, I thought that we had already moved to using threaded interrupt
handling for the urb completion a while (1-2 years ?) back. Is this then
still needed ?
We moved to handling URB completions in a tasklet, not a threaded

Right.
(Similar idea, though.) And the change was made in only one
or two HCDs, not in all of them.
Ah, I was under the impression this was a core change, not a per
hcd change.
