Remove check for non-NULL in power_supply_put (suggested by Pavel Machek). 2. Add Pavel Machek's ack. Description: ============ The reference counter of device allocated for power supply was incremented with each call to power_supply_get_by_name() and power_supply_get_by_phandle(). Add a symmetric 'put' operation so the device could be released after final put_device() call during supply unregistering. Rebased on next-20141007 + mine [1] patchset. Tested on Trats2 board (max77693 + charger manager). Kindly asking for reviewing and testing other drivers.
