Heres 2 patches to shrink object size of hwmon/pc87360 driver


1. hwmon-pc87360-use-sensor-attr-2.patch

Converts SENSOR_ATTRs to SENSOR_ATTR_2s for all sysfs-callbacks.
Also adds a number of #defines which provide values used to
initialize the sensor_device_attr_2.nr field for each sensor.



2. hwmon-pc87360-sysfs-combo-callbacks.patch

This combines individual  (show|set)_Sensor_Attr callbacks into
(show|set)_Sensor callbacks that handle all that Sensor's Attrs.
The callback routines use the .nr field to determine what attribute
they were called for.


Combining callbacks results in a non-trivial size reduction (b4, after)

13124    3224      16   16364    3fec A-3/drivers/hwmon/pc87360.ko
ie about 9%


Combining all show_X (for all X) together is possible, but would 
compromise clarity, and would save only ~ 1/5 th additional space.


These were tested against 2.6.16 + 4 patches from -mm1
(-mm1 is panic'g at boot on this NFS-root box)


Id like to see these get into -mm2
