Subject: power_supply: lp8788-charger: Fix leaked power supply on probe fail
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.
