This is mistaken; the only potential caller is: int cdns_resume(struct cdns *cdns) { /* ... */ if (cdns->roles[cdns->role]->resume) cdns->roles[cdns->role]->resume(cdns, cdns_power_is_lost(cdns)); return 0; } The argument can be true in cases outside of return from hibernation. Reflect the true meaning by renaming both arguments to `lost_power`.
