- Fix a problem with the cdevsw struct that prevented the kernel from
booting on a RAID volume. - Change 'id_foo' and 'idfoo' to 'idad_foo' and 'idadfoo'. This makes names more consistent with the devices that the code belongs to (more in line with the style used in the amr/mlx driver.) Reviewed by: jlemon
