Subject: [PATCH 4.4 178/312] power: ipaq-micro-battery: freeing the wrong variable

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')
