From ccba4ffd9eff6120a20cc7656458ac554aec4b0c Mon Sep 17 00:00:00 2001 From: Eduardo Valentin Date: Thu, 15 Aug 2013 11:34:17 -0400 Subject: drivers: thermal: make usage of CONFIG_THERMAL_HWMON optional When registering a new thermal_device, the thermal framework will always add a hwmon sysfs interface. This patch adds a flag to make this behavior optional. Now when registering a new thermal device, the caller can optionally inform if hwmon interface is desirable. This can be done by means of passing a thermal_zone_params.no_hwmon == true. In order to keep same behavior as of today, all current calls will by default create the hwmon interface.
