From 0b86a50c92e0118117224d57a9b4aa79d33d98b0 Mon Sep 17 00:00:00 2001 From: Josef Gajdusek Date: Sun, 11 May 2014 14:40:44 +0200 Subject: [PATCH] hwmon: (emc1403) fix inverted store_hyst() commit 17c048fc4bd95efea208a1920f169547d8588f1f upstream. Attempts to set the hysteresis value to a temperature below the target limit fails with "write error: Numerical result out of range" due to an inverted comparison.
