Subject[PATCH 3.11 22/94] cfg80211: fix warning when using WEXT for IBSS
Date
3.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bruno Randolf <br1@einfach.org>

commit f478f33a93f9353dcd1fe55445343d76b1c3f84a upstream.

Fix kernel warning when using WEXT for configuring ad-hoc mode,
e.g. "iwconfig wlan0 essid test channel 1"

WARNING: at net/wireless/chan.c:373 cfg80211_chandef_usable+0x50/0x21c [cfg80211]()

The warning is caused by an uninitialized variable center_freq1.
