Hi,
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/testing other drivers.
Best regards, Krzysztof
