hwmon/drivers/core: Simplify complex dependency
As the thermal framework does not longer compile as a module, we can simplify this condition below: if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \ (!defined(CONFIG_THERMAL_HWMON) || \ !(defined(MODULE) && IS_MODULE(CONFIG_THERMAL))) if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \ (!defined(CONFIG_THERMAL_HWMON) || \ !(defined(MODULE) && 0)) => (whatever && 0) = 0 if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \ (!defined(CONFIG_THERMAL_HWMON) || !(0)) if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \ (!defined(CONFIG_THERMAL_HWMON) || 1) => (whatever || 1) = 1 if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \ (1) => (whatever && 1) = whatever if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) CONFIG_THERMAL can not be a module anymore, then: if defined(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) And CONFIG_THERMAL_OF already depends on CONFIG_THERMAL, so: if defined(CONFIG_THERMAL_OF) Thus, ifdef CONFIG_THERMAL_OF Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Acked-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
