From: Arnd Bergmann Date: Mon, 15 Feb 2016 09:02:51 +0000 (+0100) Subject: iio: health/afe4403: mark suspend/resume functions __maybe_unused X-Git-Tag: v4.14-rc1~3621^2~413^2~32 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9e8be75e277a46ebbed4c37f1ee4b46ffeba5a08;p=platform%2Fkernel%2Flinux-rpi.git iio: health/afe4403: mark suspend/resume functions __maybe_unused The newly added afe4403 driver implements suspend/resume using the SIMPLE_DEV_PM_OPS() macro, which leaves out references to the actual functions when CONFIG_PM is disabled, causing a harmless warning: health/afe4403.c:509:12: error: 'afe4403_suspend' defined but not used health/afe4403.c:530:12: error: 'afe4403_resume' defined but not used This marks the functions as __maybe_unused so we don't get those warnings.
