From 1c3bae6e475fed5c570ac16fef2afe743c477886 Mon Sep 17 00:00:00 2001 From: Qianqian Xie Date: Thu, 24 Mar 2016 19:08:03 +0800 Subject: [PATCH] net: hns: remove useless variable assignment and comment The variable head in hns_nic_tx_fini_pro has read a value, but it is obviously no use. The patch will fix it. And the comment is nothing to do with the routine, so it has to be removed Signed-off-by: Qianqian Xie Signed-off-by: Yisen Zhuang Signed-off-by: David S.
