[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: rapidio: remove unnecessary use of list iterator
has been removed from the -mm tree.  Its filename was
     rapidio-remove-unnecessary-use-of-list-iterator.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: rapidio: remove unnecessary use of list iterator

req->map is set in the valid case and always equals 'map' if the break was
hit.  It therefore is unnecessary to use the list iterator variable and
the use of 'map' can be replaced with req->map.

This is done in preparation to limit the scope of a list iterator to the
list traversal loop [1].
