From: Johannes Berg <johannes.berg@xxxxxxxxx>
This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit bb512ad0732232f1d2693bb68f31a76bed8f22ae upstream.
This reverts commit 24aa11ab8ae03292d38ec0dbd9bc2ac49fe8a6dd.
That commit was wrong since it uses data that hasn't even been set
up yet, but might be a hold-over from a previous connection.
Additionally, it seems like a driver-specific workaround that
shouldn't have been in mac80211 to start with.
Fixes: 24aa11ab8ae0 ("mac80211: disable uAPSD if all ACs are under ACM")
