[PATCH] IPMI Watchdog handling updates
Makes the IPMI watchdog more consistent with the other watchdog drivers.
I have tested this and it seems to work correctly. I also added docs for
the interface change.
- support disabling watchdog by writing 'V' to device.
- unify printk()
- use atomic bit operations on ipmi_wdog_open
