[PATCH v5 18/20] power_supply: bq2415x_charger: Decrement the power supply's device reference counter

From: Krzysztof Kozlowski
Date: Fri Feb 27 2015 - 03:22:49 EST


Use power_supply_put() to decrement the power supply's device reference
counter (increased by power_supply_get_by_name() or
power_supply_get_by_phandle()).
