[v5,07/20] mfd: ab8500: Use power_supply_*() API for accessing function attrs

Commit Message

Krzysztof Kozlowski Feb. 27, 2015, 8:19 a.m. UTC

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
