From: Yuan Can <yuancan@xxxxxxxxxx> [ Upstream commit c4d33381b134da188ccd1084aef21e2b8c3c422e ] The ab8500_charger_init() returns the platform_driver_register() directly without checking its return value, if platform_driver_register() failed, all ab8500_charger_component_drivers are not unregistered. Fix by unregister ab8500_charger_component_drivers when platform_driver_register() failed.
