Merge git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-2.6: iwlwifi: fix device id registration for 6000 series 2x2 devices ath5k: update channel in sw state after stopping RX and TX rtl8187: use DMA-aware buffers with usb_control_msg mac80211: avoid NULL ptr deref when finding max_rates in PID and minstrel airo: airo_get_encode{,ext} potential buffer overflow Pulled directly by Linus because Davem is off playing shuffle-board at some Alaskan cruise, and the NULL ptr deref issue hits people and should get merged sooner rather than later. David - make us proud on the shuffle-board tournament!
