asus_atk0110: MBIF method not always present

Hi,

The asus_atk0110.c module failed to populate /sys/class/hwmon entries on this board ASUSTeK Computer INC. P5L-VM 1394 (as reported by sensors-detect) after loading the module.

After looking at the code and the ACPI DSDT, the MBIF method is not found, but the required methods for old probing are there so I made a patch that does not treat MBIF missing as fatal.

With the patch applied I can read the sensors ok:

[juan@nocturno ~]$ sensors
atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage: +1.24 V (min = +0.85 V, max = +1.60 V)

 +3.3 Voltage:   +3.26 V  (min =  +2.97 V, max =  +3.63 V)
 +5 Voltage:     +4.99 V  (min =  +4.50 V, max =  +5.50 V)
 +12 Voltage:   +12.14 V  (min = +10.20 V, max = +13.80 V)
CPU FAN Speed:  1383 RPM  (min =    0 RPM)
CPU Temperature: +24.0°C  (high = +60.0°C, crit = +95.0°C)  
MB Temperature:  +36.0°C  (high = +45.0°C, crit = +95.0°C)  

[juan@nocturno ~]$

This matches what the FreeBSD/NetBSD code does in the aiboost(4) driver (which I ported from FreeBSD to NetBSD in 2007).

The patch is against vanilla kernel-2.6.32.3 sources. Please CC me if you reply to this thread because I'm not subscribed to this list.

Thanks.
