Checkpatch also complains about this.
Can we rewrite this using if (IS_ENABLED(CONFIG...)) please ?
Please, do not relay on checkpatch that much. In this case #ifdef is better since in this case all under ifdef will be cut off while using if(...) requires all code under the if to be able to be run even if config is not enabled. Thanks.
