See https://docs.kernel.org/dev-tools/checkpatch.html, it says: Checkpatch is not always right. Your judgement takes precedence over checkpatch messages. If your code looks better with the violations, then its probably best left alone. checkpatch wants a comment for uses of memory barriers. Here I think it is a false positive.
