Date: Sun, 5 Jul 2009 09:23:21 +0200 (CEST) From: Julia Lawall <julia@...u.dk> To: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org Subject: [PATCH] drivers/net/cs89x0.c: Avoid using magic number in set_dma_mode From: Julia Lawall <julia@...u.dk> The constant DMA_RX_MODE is defined to be 0x14 in the local include file cs89x0.h. Since a constant with the same name is used elsewhere with set_dma_mode, it seems likely that this constant could be used here. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1; identifier I; constant int C; @@ ( set_dma_mode(E1,I,...) | *set_dma_mode(E1,C,...) ) // </smpl> Signed-off-by: Julia Lawall <julia@...u.dk> --- drivers/net/cs89x0.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/net/cs89x0.c b/drivers/net/cs89x0.c index 3eee666..67c9702 100644 --- a/drivers/net/cs89x0.c +++ b/drivers/net/cs89x0.c @@ -1367,7 +1367,7 @@ net_open(struct net_device *dev) spin_lock_irqsave(&lp->lock, flags); disable_dma(dev->dma); clear_dma_ff(dev->dma); - set_dma_mode(dev->dma, 0x14); /* auto_init as well */ + set_dma_mode(dev->dma, DMA_RX_MODE); /* auto_init as well */ set_dma_addr(dev->dma, isa_virt_to_bus(lp->dma_buff)); set_dma_count(dev->dma, lp->dmasize*1024); enable_dma(dev->dma); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
