From: Niklas Söderlund Date: Fri, 17 Jan 2020 16:05:54 +0000 (+0100) Subject: thermal: rcar_gen3_thermal: Remove temperature bound X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0f510a2457cbbba18a98492bab1bf540be57ebd1;p=openwrt%2Fstaging%2Fblogic.git thermal: rcar_gen3_thermal: Remove temperature bound The hardware manual states that the operation of the sensor is not guaranteed with temperatures above 125°C, not that the readings are invalid. Remove the bound check and try to deliver temperature readings even if we are outside the guaranteed operation range.
