2015-02-03ath9k: Return early for error conditionsSujith Manoharan

2015-02-03mwifiex: disable UAPSD mode when AP startsAmitkumar Karwar
When AP is started, firmware exits power save mode. This means power save manager of AP takes priority over station. Firmware stop sending periodic AWAKE events to host. We may have UAPSD enabled on station which buffers data packets until AWAKE event from firmware. Data path is unnecessarily blocked in this case. This patch disables UAPSD mode to reenable transmit data path.

2015-01-29b43: Fix locking FIXME in beacon update top halfMichael Büsch
b43 has a FIXME about locking in the mac80211 set-beacon-int callback for a long time. As it turns out there actually is a tiny race window that could result in a use-after-free bug of the 'current_beacon' memory. Nobody ever reported this, so it probably never happened. Fix this by adding a spin lock that protects the current_beacon access. We must not be in atomic context while accessing hardware (due to SDIO), so the beacon update bottom half has to clone the skb and release the lock before writing it to hardware. Let's all hope that this stops the troll who is trying to submit incorrect fixes for this issue repeatedly. And let's hope that I'm not a troll, too, who just hides even more evil code in an even more complex attempt to fix the issue.
