[PATCH v6 12/22] power_supply: charger-manager: Use power_supply_*() API for accessing function attrs

Krzysztof Kozlowski
2015-03-10T08:27:16Z

Replace direct calls to power supply function attributes with wrappers.
Wrappers provide safe access in case of unregistering the power
supply (e.g. by removing the driver). Replace:
- get_property -> power_supply_get_property
