3.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Barry Song <redacted> 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) Signed-off-by: Barry Song <redacted> Signed-off-by: Vinod Koul <redacted> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> --- drivers/dma/sirf-dma.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
