Subject: [PATCH] drm/komeda: mark PM functions as __maybe_unused
Date: Tue, 7 Jan 2020 22:53:19 +0100 [thread overview]
Message-ID: <20200107215327.1579195-1-arnd@arndb.de> (raw)
Without this, we get a couple of warnings when CONFIG_PM
is disabled:
drivers/gpu/drm/arm/display/komeda/komeda_drv.c:156:12: error: 'komeda_rt_pm_resume' defined but not used [-Werror=unused-function]
static int komeda_rt_pm_resume(struct device *dev)
^~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/arm/display/komeda/komeda_drv.c:149:12: error: 'komeda_rt_pm_suspend' defined but not used [-Werror=unused-function]
static int komeda_rt_pm_suspend(struct device *dev)
^~~~~~~~~~~~~~~~~~~~
Fixes: efb465088518 ("drm/komeda: Add runtime_pm support")
