[ 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.
Fixes: 1c1f13a006ed ("power: supply: ab8500: Move to componentized binding")
