Subject: [PATCH] iio: light: cm3605: mark PM functions as __maybe_unused
Date: Fri, 20 Jan 2017 17:25:15 +0100 [thread overview]
Message-ID: <20170120162530.3704498-1-arnd@arndb.de> (raw)
When CONFIG_PM_SLEEP is disabled, we get a harmless warning
drivers/iio/light/cm3605.c:292:12: error: 'cm3605_pm_resume' defined but not used [-Werror=unused-function]
drivers/iio/light/cm3605.c:281:12: error: 'cm3605_pm_suspend' defined but not used [-Werror=unused-function]
Marking the functions as possibly unused avoids the warning without
needing to add an #ifdef.
Fixes: 8afa505c1230 ("iio: light: add driver for Capella CM3605")
