From 699012e1775dbf7b971e9bcf3269fa83fab4aa0f Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 27 May 2014 22:33:57 +0200 Subject: mac80211: fix a memory leak on sta rate selection table MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 53d045258ee2e38b1e882617cb0799a04d05f5fa upstream. If the rate control algorithm uses a selection table, it is leaked when the station is destroyed - fix that.
