drivers/net/cs89x0.c: Avoid using magic number in set_dma_mode
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@diku.dk> Signed-off-by: David S. Miller <davem@davemloft.net>
