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

From: Greg Kroah-Hartman
Date: Fri May 08 2020 - 08:43:35 EST


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

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')
