[PATCH v4 04/20] power_supply: sysfs: Use power_supply_*() API for accessing function attrs

From: Krzysztof Kozlowski
Date: Mon Feb 23 2015 - 06:56:28 EST


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
- set_property -> power_supply_set_property
- property_is_writeable -> power_supply_property_is_writeable
