[patch 018/123] ath9k: fix keycache leak in split tkip case

From: Greg KH
Date: Fri Mar 12 2010 - 20:22:48 EST


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

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

From: Ming Lei <tom.leiming@xxxxxxxxx>

commit 733da37dab72de6b3f8b0c56b5cdea322f18a684 upstream.

If split tkip key is used, ath_delete_key should delete
rx key and rx mic key. This patch fixes the leak of hw
keycache in the case.
