From dff6d4f80509d1aaf07da9534f3f4b6876876caf Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Niklas=20S=C3=B6derlund?= Date: Fri, 17 Jan 2020 17:05:53 +0100 Subject: [PATCH] thermal: rcar_thermal: Remove temperature bound MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The hardware manual states that the operation of the sensor is not guaranteed outside the range of -45°C to 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.
