From d8e3a61318b9b18b56680bd62e93afbafae16263 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Fri, 25 May 2018 18:10:10 -0700 Subject: thermal: int340x: Prevent error in reading trip hysteresis attribute Some of the INT340X devices may not have hysteresis defined in the ACPI definition. In that case reading trip hysteresis results in error. This spams logs of user space utilities. In this case instead of returning error, just return hysteresis as 0, which is correct as there is no hysteresis defined for the device.
