From: Colin Ian King <[email protected]>
Currently if the pointer battery is null there is a null pointer
dereference on the call to power_supply_put. Fix this by only
performing the put if battery is not null.
Addresses-Coverity: ("Dereference after null check")
Fixes: 4bff91bb3231 ("power: supply: cpcap-charger: Fix missing
power_supply_put()")
