Message-ID: <20100303212638.GI23920@tuxdriver.com> Date: Wed, 3 Mar 2010 16:26:39 -0500 From: "John W. Linville" <linville@...driver.com> To: davem@...emloft.net Cc: linux-wireless@...r.kernel.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: pullreq: wireless-next-2.6 2010-03-03 Dave, Here is another quick batch intended for 2.6.34. Included are a USB ID, some small fixes, and a few (for async firmware loading and KEY_RFKILL) that depended on patches that weren't in the net-next-2.6 tree until after the merge window opened. Please let me know if there are problems! Thanks, John --- The following changes since commit 3a5b27bf6f29574d667230c7e76e4b83fe3014e0: Linus Torvalds (1): Merge branch 'for-linus' of git://gitorious.org/linux-omap-dss2/linux are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next-2.6.git master Bryan Polk (1): rt2x00: Add USB ID for CEIVA adapter to rt73usb Dan Carpenter (1): zd1211rw: fix potential array underflow Helmut Schaa (2): rt2x00: fix rt2800pci compilation with SoC rt2x00: Export rt2x00soc_probe from rt2x00soc Johannes Berg (2): ar9170: load firmware asynchronously iwlwifi: load firmware asynchronously before mac80211 registration Jouni Malinen (1): mac80211: Fix reassociation processing (within ESS roaming) Matthew Garrett (1): rfkill: Add support for KEY_RFKILL Ming Lei (1): ath9k: fix lockdep warning when unloading module Stanislaw Gruszka (1): airo: return from set_wep_key() when key length is zero Sujith (1): mac80211: Fix HT rate control configuration drivers/net/wireless/airo.c | 3 +- drivers/net/wireless/ath/ar9170/ar9170.h | 1 + drivers/net/wireless/ath/ar9170/main.c | 10 ++- drivers/net/wireless/ath/ar9170/usb.c | 170 ++++++++++++++++++------------ drivers/net/wireless/ath/ath9k/rc.c | 6 +- drivers/net/wireless/ath/ath9k/xmit.c | 4 +- drivers/net/wireless/iwlwifi/iwl-agn.c | 157 ++++++++++++++-------------- drivers/net/wireless/iwlwifi/iwl-dev.h | 2 + drivers/net/wireless/rt2x00/rt2800pci.c | 2 +- drivers/net/wireless/rt2x00/rt2x00soc.c | 1 + drivers/net/wireless/rt2x00/rt73usb.c | 2 + drivers/net/wireless/zd1211rw/zd_mac.c | 10 +- include/linux/rfkill.h | 2 +- include/net/mac80211.h | 3 +- net/mac80211/mlme.c | 19 +++- net/mac80211/rate.h | 5 +- net/rfkill/input.c | 8 ++ 17 files changed, 237 insertions(+), 168 deletions(-) diff --git a/drivers/net/wireless/airo.c b/drivers/net/wireless/airo.c index 698d567..dc5018a 100644 --- a/drivers/net/wireless/airo.c +++ b/drivers/net/wireless/airo.c @@ -5255,7 +5255,8 @@ static int set_wep_key(struct airo_info *ai, u16 index, const char *key, WepKeyRid wkr;
