From: Eduardo Valentin
Date: Tue Nov 08 2016 - 00:12:03 EST


Remove the following warning:
In file included from drivers/thermal/thermal_sysfs.c:19:0:
include/linux/device.h:575:26: warning: âdev_attr_emul_tempâ defined but not used [-Wunused-variable]
struct device_attribute dev_attr_##_name = __ATTR(_name, _mode, _show, _store)
^
drivers/thermal/thermal_sysfs.c:395:8: note: in expansion of macro âDEVICE_ATTRâ

when emul temp is disabled at Kconfig.
