[ patch .24-rc0 5/5 ] SuperIO locks coordinator - use in other hwmon/*.c

From: Jim Cromie
Date: Mon Oct 15 2007 - 01:11:32 EST


05 - use superio-locks in rest of drivers/hwmon/*.c

this patch is compile-tested only, please review for sanity before you try running them. Things to look for - missing superio_release(),
opportunities to use superio_devid(), superio_inw(), etc.
