[PATCH v6 09/22] mfd: ab8500: Use power_supply_*() API for accessing function attrs

Krzysztof Kozlowski
2015-03-10T08:27:13Z

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
