If CONFIG_PM is n, gcc warns:

drivers/media/platform/marvell-ccic/mmp-driver.c:347:12: warning: ‘mmpcam_resume’ defined but not used [-Wunused-function]
 static int mmpcam_resume(struct device *dev)
            ^~~~~~~~~~~~~
drivers/media/platform/marvell-ccic/mmp-driver.c:338:12: warning: ‘mmpcam_suspend’ defined but not used [-Wunused-function]
 static int mmpcam_suspend(struct device *dev)
            ^~~~~~~~~~~~~~
drivers/media/platform/marvell-ccic/mmp-driver.c:324:12: warning: ‘mmpcam_runtime_suspend’ defined but not used [-Wunused-function]
 static int mmpcam_runtime_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~
drivers/media/platform/marvell-ccic/mmp-driver.c:310:12: warning: ‘mmpcam_runtime_resume’ defined but not used [-Wunused-function]
 static int mmpcam_runtime_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~

Mark them as __maybe_unused to fix this.
