You need to apply these old patches:
i8k: Add support for temperature sensor labels
i8k: Register only temperature sensors which have labels
i8k: Return -ENODATA for invalid temperature
i8k: Rework error retries

(they are not in 3.18/3.19 yet, but you already reviewed them)

And after that you need to apply new pach which I sent hour ago:
[PATCH] i8k: Make fan module parameters an unsigned
