power: supply: charger-manager: Fix a NULL pointer dereference in 'charger_manager_probe()'
'devm_kzalloc()' can return NULL. Return -ENOMEM in this case in order to avoid a NULL pointer dereference later on. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
