From ef0657c49e0f93dcebc9b4719e4fe0b478411f60 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 6 Jul 2009 19:09:50 -0700 Subject: 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/) // @@ expression E1; identifier I; constant int C; @@ ( set_dma_mode(E1,I,...) | *set_dma_mode(E1,C,...) ) // Signed-off-by: Julia Lawall Signed-off-by: David S.
