This is crying for at least two separate patches, and ideally more like
3 or 4.

Additionally, I can't apply your patch to my tree. Presumably you are
missing recent patches that went into Mark's hwmon-testing tree and
which affect the lm75 driver:

hwmon: Allow writing of negative trigger temperatures
http://lm-sensors.org/kernel?p=kernel/mhoffman/hwmon-2.6.git;a=commit;h=a1efde3fd7b3d94c942b1a675da992c8a2f1f04b

hwmon: Convert from class_device to device
http://lm-sensors.org/kernel?p=kernel/mhoffman/hwmon-2.6.git;a=commit;h=f89523a27def89ddc74d094a0910970f6a1c6f43

If you split your patch and make sure that the result applies on top of
the above patches, I'll be happy to review and test your work.
