Subject: pull request: wireless 2011-09-15
Dave,
Here is a batch of fixes intended for 3.1. Included is a calibration
fix for ath9k that avoids a hang, a couple of rtlwifi fixes for
connection failures, a mac80211 locking fix, a couple of iwlagn fixes
(including a corruption fix), an ath9k oops fix, an initialization
fix for AR9330 hardware in ath9k, and a patch to avoid a needless
BUG_ON in iwlegacy.
Please let me know if there are problems!
Thanks,
John
