From 6be2a3a0769849d234ef830617c5a7235b8f48e8 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 2 Mar 2016 16:58:53 +0100 Subject: [PATCH] pinctrl: at91: use __maybe_unused to hide pm functions The at91-pio4 pinctrl driver uses SET_SYSTEM_SLEEP_PM_OPS() to conditionally set the correct suspend/resume options, but they become unused when CONFIG_PM is disabled: drivers/pinctrl/pinctrl-at91-pio4.c:827:12: error: 'atmel_pctrl_suspend' defined but not used [-Werror=unused-function] drivers/pinctrl/pinctrl-at91-pio4.c:847:12: error: 'atmel_pctrl_resume' defined but not used [-Werror=unused-function] This adds __maybe_unused annotations so the compiler knows it can silently drop them instead of warning.
