Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless
John W. Linville says: ==================== A few stragglers hoping for 3.9, somewhat delayed due to my travels... On the mac80211 bits, Johannes says: "Sadly, I have another pull request -- the idle handling fix broke LED handling in some cases." and: "Yet one more! This fixes a fairly important/annoying bug -- when roaming between multiple APs of the same network, the system could get stuck thinking it was connected to the old one while it really wasn't." On top of that... Arend sends a brcmfmac patch that removes advertising a feature that isn't actually fully supported, and a brcmsmac patch that rearranges code to request firmware at IFF_UP to play more nicely with being built into the kernel. Felix gives us a minor ath9k_htc fix to support the newly released open source firmware, and an ath9k_hw initvals fix to improve device stability. Rafał Miłecki provides a fix for an ssb regression that caused a serious performance problem with b43. Zefir Kurtisi offers an ath9k fix to change some kmalloc flags to allow the DFS detector to be called in softirq context. Please let me know if there are problems. If these don't make 3.9, I'll just pull them into wireless-next -- just let me know if you want to do it that way! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
