From: Guenter Roeck Date: Mon, 4 Jul 2016 15:27:38 +0000 (-0700) Subject: hwmon: (lm95241) Use more accurate limits X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=637ab157d4a94145a6c9b89113222b6c80fab54c;p=linux-beck.git 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.
