komeda_rt_pm_suspend() and komeda_rt_pm_resume() are compiled only when
CONFIG_PM is enabled. Having it disabled triggers the following warning
at compile time:
linux/drivers/gpu/drm/arm/display/komeda/komeda_drv.c:156:12:
warning: ‘komeda_rt_pm_resume’ defined but not used [-Wunused-function]
static int komeda_rt_pm_resume(struct device *dev)
^~~~~~~~~~~~~~~~~~~
linux/drivers/gpu/drm/arm/display/komeda/komeda_drv.c:149:12:
warning: ‘komeda_rt_pm_suspend’ defined but not used [-Wunused-function]
static int komeda_rt_pm_suspend(struct device *dev)
Make komeda_rt_pm_suspend() and komeda_rt_pm_resume() dependent on
CONFIG_PM to address the issue.
