Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless
John W. Linville says: ==================== This batch of fixes is intended for the 3.7 stream... This includes a pull of the Bluetooth tree. Gustavo says: "A few important fixes to go into 3.7. There is a new hw support by Marcos Chaparro. Johan added a memory leak fix and hci device index list fix. Also Marcel fixed a race condition in the device set up that was prevent the bt monitor to work properly. Last, Paulo Sérgio added a fix to the error status when pairing for LE fails. This was prevent userspace to work to handle the failure properly." Regarding the mac80211 pull, Johannes says: "I have a locking fix for some SKB queues, a variable initialization to avoid crashes in a certain failure case, another free_txskb fix from Felix and another fix from him to avoid calling a stopped driver, a fix for a (very unlikely) memory leak and a fix to not send null data packets when resuming while not associated." Regarding the iwlwifi pull, Johannes says: "Two more fixes for iwlwifi ... one to use ieee80211_free_txskb(), and one to check DMA mapping errors, please pull." On top of that, Johannes also included a wireless regulatory fix to allow 40 MHz on channels 12 and 13 in world roaming mode. Also, Hauke Mehrtens fixes a #ifdef typo in brcmfmac. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
