From 0b351c986a5ffedb502632c1b27690c9730d79c4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 20 Jan 2017 17:24:30 +0100 Subject: [PATCH] PCI: rockchip: Mark PM functions as __maybe_unused When CONFIG_PM_SLEEP is disabled, we get harmless build warnings: host/pcie-rockchip.c:1267:12: error: 'rockchip_pcie_resume_noirq' defined but not used [-Werror=unused-function] host/pcie-rockchip.c:1240:12: error: 'rockchip_pcie_suspend_noirq' defined but not used [-Werror=unused-function] Marking both functions as __maybe_unused avoids the warning without the need for #ifdef around them.
