[PATCH 2/3] dmaengine: sirf: fix a typo in moving running dma_desc to active queue
From: Barry Song <hidden>
Date: 2012-09-27 08:36:10
From: Barry Song <redacted> 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> --- drivers/dma/sirf-dma.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
