Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless
John says: -------------------- I apologize for not having sent this sooner. FWIW, I was in a car somewhere between Illinois and North Carolina for most of the day Sunday and Monday... :-) This is (obviously) the last non-fix pull request for wireless bits intended for 3.5. It includes AP support for mwifiex, a variety of HCI and other updates for NFC, some brcmfmac and brcmsmac refactoring, a large batch of ssb and bcma updates, a batch of ath6kl updates, some cfg80211 and mac80211 updates/refactoring from Johannes Berg, a rather large collection of Bluetooth updates by way of Gustavo, and a variety of other bits here and there. -------------------- Signed-off-by: David S. Miller <davem@davemloft.net>
