To improve this further, also use the pm_ptr() helper that lets the dev_pm_ops get dropped entirely when CONFIG_PM is disabled. A related mistake happened in the of_match_ptr() macro here, which like SET_RUNTIME_PM_OPS() requires the match table to be marked as __maybe_unused, though I could not reproduce building this without CONFIG_OF. Remove the of_match_ptr() here as there is no point in dropping the match table in configurations without CONFIG_OF.
