Subject: iio: mlx96014: Replace offset sign
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c68a67b7adeec240bd79780635dc0ce74d0cb61a;p=linux-beck.git

iio: mlx96014: Replace offset sign

Changed the offset to negative as usual equation is: (raw +
offset)*scale and in this
case offset should be negative (as we deduct 273.15 Kelvin to get temperature
in Celsius).
