Date: Sun, 7 Aug 2016 16:32:00 -0700 From: Guenter Roeck <linux@...ck-us.net> To: Jean Delvare <jdelvare@...e.com> Cc: linux-hwmon@...r.kernel.org, linux-kernel@...r.kernel.org, Guenter Roeck <linux@...ck-us.net> Subject: [PATCH 6/6] hwmon: (lm95241) Use more accurate limits The lower temperature limit is -128 degrees C. The supported upper limits are 127.875 or 255.875 degrees C. Also, don't fail if a value outside the supported range is provided when setting a temperature limit. Instead, clamp the provided value to the available value range.
