acpi_thinkpad(4): make acpi_thinkpad sensors actually work
* After this patch on my ThinkPad R51:
%sysctl hw.sensors.acpi_ibm0
hw.sensors.acpi_ibm0.temp0: 69.00 degC
hw.sensors.acpi_ibm0.temp1: 52.00 degC
hw.sensors.acpi_ibm0.temp2: 41.00 degC
hw.sensors.acpi_ibm0.temp3: 59.00 degC
hw.sensors.acpi_ibm0.temp4: 36.00 degC
hw.sensors.acpi_ibm0.temp5: invalid
hw.sensors.acpi_ibm0.temp6: 26.00 degC
hw.sensors.acpi_ibm0.temp7: invalid
hw.sensors.acpi_ibm0.fan0: 3469 RPM
* Before this patch:
o The temperature values were absolutely random, since
the /data/ variable was never initialised from temp[i].
o The braces were missing from the fan error path of
an if statement.
o Whitespaces were used instead of tabs.
