From 2a32ca138e24836d01918797018b0fd0302c6b3f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 7 Aug 2017 12:41:53 +0200 Subject: [PATCH] hns3: fix unused function warning Without CONFIG_PCI_IOV, we get a harmless warning about an unused function: drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.c:2273:13: error: 'hclge_disable_sriov' defined but not used [-Werror=unused-function] The #ifdefs in this driver are obviously wrong, so this just removes them and uses an IS_ENABLED() check that does the same thing correctly in a more readable way.
