John W. Linville says:

====================
This batch of fixes is intended for 3.6...

Johannes Berg gives us a pair of iwlwifi fixes.  One corrects some
improperly defined ifdefs that lead to crashes and BUG_ONs.  The other
prevents attempts to read SRAM for devices that aren't actually started.

Julia Lawall provides an ipw2100 fix to properly set the return code
from a function call before testing it! :-)

Thomas Huehn corrects the improper use of a constant related to a power
setting in ath5k.

Thomas Pedersen offers a mac80211 fix to properly handle destination
addresses of unicast frames passing though a mesh gate.

Vladimir Zapolskiy provides a brcmsmac fix to properly mark the
interface state when the device goes down.
