From 58359193193c4261d340b2f7f028e5096d4e4d15 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 18 Jan 2018 14:04:42 +0100 Subject: [PATCH] can: m_can: mark runtime-PM handlers as __maybe_unused Building without CONFIG_PM results in a harmless warning: drivers/net/can/m_can/m_can.c:1763:12: error: 'm_can_runtime_resume' defined but not used [-Werror=unused-function] drivers/net/can/m_can/m_can.c:1752:12: error: 'm_can_runtime_suspend' defined but not used [-Werror=unused-function] Marking the functions as __maybe_unused lets the compiler silently drop them instead.
