3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Barry Song <baohua.s...@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)
or
list_move_tail(&sdesc->node, &schan->active)
