4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@xxxxxxxxx>
commit e6436be21e77e3659b4ff7e357ab5a8342d132d2 upstream.
In the case that dev_alloc_name() fails, e.g. because the name was
given by the user and already exists, we need to clean up properly
and free the per-CPU statistics. Fix that.
Fixes: 5a490510ba5f ("mac80211: use per-CPU TX/RX statistics")
