From 1bd09f869f9b294b5645e2ac153ee59604ef959e Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 23 Dec 2018 09:57:07 +0100 Subject: dmaengine: dw: drop useless LIST_HEAD Drop LIST_HEAD where the variable it declares is never used. Commit ab703f818ac3 ("dmaengine: dw: lazy allocation of dma descriptors") removed the uses, but not the declaration. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // @@ identifier x; @@ - LIST_HEAD(x); ... when != x // Fixes: ab703f818ac3 ("dmaengine: dw: lazy allocation of dma descriptors") Signed-off-by: Julia Lawall Signed-off-by: Vinod Koul --- drivers/dma/dw/core.c | 1 - 1 file changed, 1 deletion(-) (limited to 'drivers/dma/dw/core.c') diff --git a/drivers/dma/dw/core.c b/drivers/dma/dw/core.c index dc053e62f894..290d21be4d4c 100644 --- a/drivers/dma/dw/core.c +++ b/drivers/dma/dw/core.c @@ -1150,7 +1150,6 @@ static void dwc_free_chan_resources(struct dma_chan *chan) struct dw_dma_chan *dwc = to_dw_dma_chan(chan); struct dw_dma *dw = to_dw_dma(chan->device); unsigned long flags; - LIST_HEAD(list); dev_dbg(chan2dev(chan), "%s: descs allocated=%u\n", __func__, dwc->descs_allocated); -- cgit v1.2.3
