2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------
From: Rajkumar Manoharan <rmano...@qca.qualcomm.com>
[ upstream commit 676b58c27475a9defccc025fea1cbd2b141ee539 ]
A panic was observed when the device is failed to resume properly,
and there are no running interfaces. ieee80211_reconfig tries
to restart STA timers on unassociated state.
