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.

I'm not sure if we should support power_supply_put(NULL), but
otherwise the series looks ok to me.
