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 <Julia.Lawall@lip6.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
