When CONFIG_PM_SLEEP is disabled, we get a couple of harmless warnings: drivers/net/ethernet/renesas/ravb_main.c:2117:12: error: 'ravb_resume' defined but not used [-Werror=unused-function] drivers/net/ethernet/renesas/ravb_main.c:2104:12: error: 'ravb_suspend' defined but not used [-Werror=unused-function] The simplest solution here is to replace the #ifdef with __maybe_unused annotations, which lets the compiler do the right thing by itself.
