From db59b464f8708cdba857f16b183cff0b7466d6b5 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Thu, 31 Aug 2006 14:18:39 -0400 Subject: uhci-hcd: fix list access bug When skipping to the last TD of an URB, go to the _last_ entry in the list instead of the _first_ entry (as780). This fixes Bugzilla #6747 and possibly others.
