Subject: hwmon: (ibmaem) add missing kfree
From: Julia Lawall <ju...@diku.dk>
commit 66a89b2164e2d30661edbd1953eacf0594d8203a upstream.
rs_resp is dynamically allocated in aem_read_sensor(), so it should be freed
before exiting in every case. This collects the kfree and the return at
the end of the function.
