Reading or Setting Fan curves does not work [BUG] #90

Problem Descripition
I was going through the tests to verify if the kernelmodule was working correctly. The fancurve output is all zeros for all the fans, which should not be the case. Also, when I try to modify the fan curve in the test, fan 2 does not change and remains zero.

FYI: There were a lot of ACPI errors when I ran sudo make reloadmodule. The module did load in the end.
