[PATCH RESEND v2 0/7] power_supply: Decrement the device reference counter

[Krzysztof Kozlowski]

Hi,


Resending with some new acks.
Whole patchset should be taken at once (everything depends on patch 1).
Depends on [1].


Changes since v1:
=================
1. 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-20141104 + mine [1] patchset.
Tested on Trats2 board (max77693 + charger manager).

Kindly asking for reviewing and testing other drivers.

Best regards,
Krzysztof
