The tegra driver can be compiled without CONFIG_PM_SLEEP enabled.
In this case the compilation triggers the warning below:
drivers/gpu/drm/tegra/sor.c:3984:12: warning: ‘tegra_sor_resume’
defined but not used [-Wunused-function]
3984 | static int tegra_sor_resume(struct device *dev)
| ^~~~~~~~~~~~~~~~
drivers/gpu/drm/tegra/sor.c:3970:12: warning: ‘tegra_sor_suspend’
defined but not used [-Wunused-function]
3970 | static int tegra_sor_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~~~
Fix the warning adding __maybe_unused to the PM functions.
