Subject: [PATCH 1/2] ia64: Use ARRAY_SIZE to replace its implementation
Date: Tue, 14 Aug 2018 10:46:53 +0800 [thread overview]
Message-ID: <1534214814-9043-2-git-send-email-zhongjiang@huawei.com> (raw)
In-Reply-To: <1534214814-9043-1-git-send-email-zhongjiang@huawei.com>
We prefer to ARRAY_SIZE rather than duplicating its implementation.
So just replace it.
