genpd_syscore_switch() had two problems: 1. It silently assumed that device, it is being called for, belongs to generic power domain and used container_of() on its power domain pointer. Such assumption might not be true always. 2. It iterated over list of generic power domains without holding gpd_list_lock mutex thus list could have been modified at the same time. Usage of genpd_lookup_dev() solves both problems as it is safe a call for non-generic power domains and uses mutex when iterating.
