* NFC: Do not take the genl mutex from the netlink release notifierSamuel Ortiz2011-12-141-2/+0
| | | | | | | | | The netlink notifier is atomic so we must not sleep in that context. Also we know that Any netlink packets arriving to us will be purged when the notifier is called, so we don't need to take the mutex.

* mwifiex: remove cfg_workqueueAmitkumar Karwar2011-12-146-158/+75
| | | | | | | | | | | | | | | | | | | | | | | cfg_workqueue was added to notify cfg80211 that scan, connect or disconnect is done by calling respective completion handlers. We can avoid use of this workqueue by calling those handlers from other places. 1) Call connect, disconnect completion handlers in their callback functions. ex. Call cfg80211_connect_result() in mwifiex_cfg80211_connect() 2) Call scan completion handler after parsing response of last scan command in a queue. After removing the workqueue, variables (assoc_request etc.) and checks used for mutual exclusion become redundant. Those are also removed in this patch.

The first fix for this problem did not solve it on all devices. commit 6ae8ec27868bfdbb815287bee8146acbefaee867 Author: Rafał Miłecki <zajec5@gmail.com> Date: Tue Jul 5 17:25:32 2011 +0200 ssb: fix init regression of hostmode PCI core In ssb_pcicore_fix_sprom_core_index() the sprom on the PCI core is accessed, but the sprom only exists when the ssb bus is connected over a PCI bus to the rest of the system and not when the SSB Bus is the main system bus. SoCs sometimes have a PCI host controller and there this code will not be executed, but there are some old SoCs with an PCI controller in client mode around and ssb_pcicore_fix_sprom_core_index() should not be called on these devices too. The PCI controller on these devices are unused, but without this fix it results in an Data bus error when it gets initialized.

| * mac80211: fix another race in aggregation startJohannes Berg2011-12-071-45/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Emmanuel noticed that when mac80211 stops the queues for aggregation that can leave a packet pending. This packet will be given to the driver after the AMPDU callback, but as a non-aggregated packet which messes up the sequence number etc. I also noticed by looking at the code that if packets are being processed while we clear the WANT_START bit, they might see it cleared already and queue up on tid_tx->pending. If the driver then rejects the new aggregation session we leak the packet. Fix both of these issues by changing this code to not stop the queues at all. Instead, let packets queue up on the tid_tx->pending queue instead of letting them get to the driver, and add code to recover properly in case the driver rejects the session. (The patch looks large because it has to move two functions to before their new use.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Leaving leisure power save mode can take some time, so it's better to perform that action in process context with interrupts enabled. This patch changes lps_leave tasklet to work.
