Subject[PATCH v3 10/20] power_supply: charger-manager: Use power_supply_*() API for accessing function attrs
Date
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
