I think you asked for the following patches:

56c5485c9e44 ("ath: Use safer key clearing with key cache entries")
73488cb2fa3b ("ath9k: Clear key cache explicitly on disabling hardware")
d2d3e36498dd ("ath: Export ath_hw_keysetmac()")
144cd24dbc36 ("ath: Modify ath_key_delete() to not need full key entry")
ca2848022c12 ("ath9k: Postpone key cache entry deletion for TXQ frames
reference it")

And I can see they are already in the queue for next v4.19.y release,
so should be part of v4.19.205
