From e58c5de8f59d124907c993ea3126c69493b7eec7 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 12 Jun 2012 10:17:25 -0400 Subject: [PATCH] drivers/ide/ide-cs.c: adjust suspicious bit operation IO_DATA_PATH_WIDTH_8 is 0, so a bit-and with it is always false. The value IO_DATA_PATH_WIDTH covers the bits of the IO_DATA_PATH constants, so first pick those bits and then make the test using !=. This problem was found using Coccinelle (http://coccinelle.lip6.fr/). Signed-off-by: Julia Lawall Signed-off-by: David S.
