Subject: [PATCHv4 40/48] thermal: sysfs: remove symbols of emul_temp when config is disabled
Remove the following warning:
In file included from drivers/thermal/thermal_sysfs.c:19:0:
include/linux/device.h:575:26: warning: ‘dev_attr_emul_temp’ 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 ‘DEVICE_ATTR’
when emul temp is disabled at Kconfig.
