From 4f194969c3b01ab080d38114feb09be05b16d7c3 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 23 Dec 2018 09:57:12 +0100 Subject: [PATCH] dmaengine: pl330: drop useless LIST_HEAD Drop LIST_HEAD where the variable it declares is never used. The variable has not been used since the function was introduced in 740aa95703c5 ("dmaengine: pl330: Split device_control"). The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // @@ identifier x; @@ - LIST_HEAD(x); ... when != x // Fixes: 740aa95703c5 ("dmaengine: pl330: Split device_control") Signed-off-by: Julia Lawall Signed-off-by: Vinod Koul --- drivers/dma/pl330.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/dma/pl330.c b/drivers/dma/pl330.c index cff1b143fff5..eec79fdf27a5 100644 --- a/drivers/dma/pl330.c +++ b/drivers/dma/pl330.c @@ -2267,7 +2267,6 @@ static int pl330_terminate_all(struct dma_chan *chan) struct dma_pl330_desc *desc; unsigned long flags; struct pl330_dmac *pl330 = pch->dmac; - LIST_HEAD(list); bool power_down = false; pm_runtime_get_sync(pl330->ddma.dev);
