New Revision: 183832
URL: http://svn.freebsd.org/changeset/base/183832

Log:
  The linux list compat code had an error which prevented list_for_each_safe()
  from operating on a list with a single item.  This code is used much more by
  the i915 driver with xorg-7.4.  Correct it to match the actual linux
  implementation.
