From 0f510a2457cbbba18a98492bab1bf540be57ebd1 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Niklas=20S=C3=B6derlund?= Date: Fri, 17 Jan 2020 17:05:54 +0100 Subject: [PATCH] thermal: rcar_gen3_thermal: Remove temperature bound MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
