[PATCH V2 net-next 5/9] net: hns3: remove a redundant hclge_cmd_csq_done
From: Peng Li
Date: Mon Jul 02 2018 - 03:20:53 EST
From: Huazhong Tan <tanhuazhong@xxxxxxxxxx>
Set complete in the first hclge_cmd_csq_done of hclge_cmd_send,
and check if complete later, unnecessary to do hclge_cmd_csq_done
again.
