-Subject: [PATCH 1/2] ath9k: fix race with IEEE80211_CONF_PS checks
-
-There is a small window where the mac80211 changes the IEEE80211_CONF_PS
-flag, and then informs the driver about the change. We have a race
-condition if we are checking the flag in the same time. Avoid it by
-introducing a local variable, and using that instead of checking the
-IEEE80211_CONF_PS flag directly.
-
-This fix the problem reported by Luis:
