From 86c85e1fc4ca1f4f8bfa1c2c706b173bd460b8a1 Mon Sep 17 00:00:00 2001 From: zhong jiang Date: Wed, 19 Sep 2018 19:32:10 +0800 Subject: [PATCH] net: iucv: Use FIELD_SIZEOF directly instead of reimplementing its function FIELD_SIZEOF is defined as a macro to calculate the specified value. Therefore, We prefer to use the macro rather than calculating its value. Signed-off-by: zhong jiang Signed-off-by: David S.
