Commit Message

Dr. David Alan Gilbert Dec. 24, 2024, 1:32 a.m. UTC 
From: "Dr. David Alan Gilbert" <linux@treblig.org>

The last use of ieee80211_debugfs_key_sta_del() was removed in 2007 by
commit 11a843b7e160 ("[MAC80211]: rework key handling")

The last use of ieee80211_debugfs_key_add_mgmt_default() was removed
in 2010 by
commit f7e0104c1a4e ("mac80211: support separate default keys")

The last use of ieee80211_debugfs_key_add_beacon_default() was
removed in 2020 by
commit e5473e80d467 ("mac80211: Support BIGTK configuration for Beacon
protection")

Remove them.
