From 0e6071ab766be1b29c88c1e28bb3ed101cb10f93 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 15 Feb 2016 10:19:04 +0100 Subject: [PATCH] iio: health/afe4404: mark suspend/resume functions __maybe_unused The newly added afe4404 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/afe4404.c:509:12: error: 'afe4404_suspend' defined but not used health/afe4404.c:530:12: error: 'afe4404_resume' defined but not used This marks the functions as __maybe_unused so we don't get those warnings.
