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!
