Hi Konrad,

Thanks for the patch and sorry for the delay. A few nits below.

Is this intentional? To use priv->sensor[i].slope before computing it

		You can drop the loop, right? Because you have initialized it above.

I don't really like this check. But then there is no other way in 
tsens_priv to distinguish btw 8992 and 8994. So let us leave it as is.
