Subject: [PATCH 3.16.y-ckt 055/183] power_supply: 88pm860x: Fix leaked power supply on probe fail

3.16.7-ckt8 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Krzysztof Kozlowski <k.kozlowski@...sung.com>

commit 24727b45b484e8937dcde53fa8d1aa70ac30ec0c upstream.

Driver forgot to unregister power supply if request_threaded_irq()
failed in probe(). In such case the memory associated with power supply
leaked.
