3.5.7u1 -stable review patch.  If anyone has any objections, please let me know.


From: Barry Song <Baohua.Song@csr.com>

commit 26fd12209c08fe947be1828896ef4ffc5bd0e6df upstream.

list_move_tail(&schan->queued, &schan->active) makes the list_empty(schan->queued)
undefined, we either should change it to:
list_move_tail(schan->queued.next, &schan->active)
list_move_tail(&sdesc->node, &schan->active)
