4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

From: Dan Carpenter <dan.carpenter@...cle.com>

commit b9223da41794030a5dfd5106c34ed1b98255e2ae upstream.

We accidentally free "micro_ac_power" which is an error pointer and it
leads to an oops.  We intended to free "micro_batt_power".

Fixes: a2c1d531854c ('power_supply: ipaq_micro_battery: Check return values in probe')
