Subject: [PATCH] net: iucv: Use FIELD_SIZEOF directly instead of reimplementing its function
Date: Wed, 19 Sep 2018 17:52:13 +0800 [thread overview]
Message-ID: <1537350733-44276-1-git-send-email-zhongjiang@huawei.com> (raw)
FIELD_SIZEOF is defined as a macro to calculate the specified vaule. Therefore,
We prefer to use the macro rather than calculating its vaule.
