From: Xiongfeng Wang <wangxiongfeng2@huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4QKQ3 --------------------------- After using io_stop_wc(), drivers reports following compile error when compiled on X86. drivers/net/ethernet/hisilicon/hns3/hns3_enet.c: In function ‘hns3_tx_push_bd’: drivers/net/ethernet/hisilicon/hns3/hns3_enet.c:2058:12: error: expected ‘;’ before ‘(’ token io_stop_wc(); ^ It is because I missed to add the brackets after io_stop_wc macro. So let's add the missing brackets.
