From 65c72291f709fe8a82e1df3d7b8d2e65d4d861a6 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 28 Jul 2020 09:41:53 +0800 Subject: [PATCH] ice: mark PM functions as __maybe_unused In certain configurations without power management support, the following warnings happen: drivers/net/ethernet/intel/ice/ice_main.c:4214:12: warning: 'ice_resume' defined but not used [-Wunused-function] 4214 | static int ice_resume(struct device *dev) | ^~~~~~~~~~ drivers/net/ethernet/intel/ice/ice_main.c:4150:12: warning: 'ice_suspend' defined but not used [-Wunused-function] 4150 | static int ice_suspend(struct device *dev) | ^~~~~~~~~~~ Mark these functions as __maybe_unused to make it clear to the compiler that this is going to happen based on the configuration, which is the standard for these types of functions.
