Subject: [PATCH] drm/komeda: mark PM functions as __maybe_unused
Date:   Tue,  7 Jan 2020 22:53:19 +0100

Precedence: bulk

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)
            ^~~~~~~~~~~~~~~~~~~

 static int komeda_rt_pm_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~
