88pm860x_battery: Eliminate possible references to released resources
devm_kzalloc should not be followed by kfree, as this results in a double
free. The problem was found using the following semantic match
(http://coccinelle.lip6.fr/):
// <smpl>
@@
expression x,e;
@@
x = devm_kzalloc(...)
... when != x = e
?-kfree(x,...);
// </smpl>
Furthermore, in the remove function, the calls to free_irq are moved up to
prevent a possible reference in the interrupt handler to resources freed by
power_supply_unregister.
