From 74401773f80b6d42f7a4c6994ca0cca883b03745 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 19 Jan 2010 20:51:32 +0100 Subject: ath9k: fix beacon slot/buffer leak When cleaning up beacon buffers and slots, ath9k currently checks if sc->ah->opmode is set to a beacon related mode before cleaning up buffers. An unfortunate ordering of interface up/down commands can lead to sc->ah->opmode being set to monitor mode, while there are AP interfaces present on the same wiphy. Always cleaning up beacon buffers if present fixes this issue. Signed-off-by: Felix Fietkau Cc: stable@kernel.org Signed-off-by: John W.

According to tests by Jorge Boncompte, this breaks at least some 2GHz-only cards, so the code should be changed back to the unconditional INI fixup.
