Subject: [PATCH 13/23] freescale: ethernet: remove unnecessary unlikely()
Date: Fri, 31 Aug 2018 01:34:19 +0300	[thread overview]
Message-ID: <20180830223429.30051-14-igor.stoppa@huawei.com> (raw)
In-Reply-To: <20180830223429.30051-1-igor.stoppa@huawei.com>

Both WARN_ON() and WARN_ONCE() already contain an unlikely(), so it's not
necessary to wrap it into another.
