[PATCH 3.10 15/65] power_supply: lp8788-charger: Fix leaked power supply on probe fail

[Greg Kroah-Hartman]

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

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

From: Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx>

commit a7117f81e8391e035c49b3440792f7e6cea28173 upstream.

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