From 4b58c37bb9d4282446f7a0194dbc44325787ac8c Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 8 Jul 2015 15:41:48 +0300 Subject: [PATCH] mac80211: remove ieee80211_aes_cmac_calculate_k1_k2() The iwlwifi driver was the only driver that used this, but as it turns out it never needed it, so we can remove it.
