Subject: pull request: wireless 2011-11-22 #2
Dave,
Here is the latest batch of fixes intended for 3.2. This includes a
correction for a user-visible error in mac80211's debugfs info, a fix
for a potential memory corrupter in prism54, an endian fix for rt2x00,
an endian fix for mac80211, a fix for a NULL derefernce in cfg80211, a
locking fix for p54spi and a deadlock fix also for p54spi.
This reverts the problematic rt2x00 patches from the earlier pull
request.
Please let me know if there are problems!
Thanks,
John
