[PATCH 4.11 04/84] mac80211: free netdev on dev_alloc_name() error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

------------------

From: Johannes Berg <johannes.berg@xxxxxxxxx>


[ Upstream commit c7a61cba71fd151cc7d9ebe53a090e0e61eeebf3 ]

The change to remove free_netdev() from ieee80211_if_free()
erroneously didn't add the necessary free_netdev() for when
ieee80211_if_free() is called directly in one place, rather
than as the priv_destructor. Add the missing call.

Fixes: cf124db566e6 ("net: Fix inconsistent teardown and release of private netdev state.")
