Subject: [PATCH 01/14] pinctrl: at91: use __maybe_unused to hide pm functions
Date: Wed,  2 Mar 2016 16:58:53 +0100	[thread overview]
Message-ID: <1456934350-1389172-2-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1456934350-1389172-1-git-send-email-arnd@arndb.de>

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.
