commit de312db345f9770b64ff39ef5a7f86f6358e93cc

Dave,

I have a few more small fixes, hopefully still in time for 3.4-rc1...

Rajkukmar provides us with a one-line timestamp correction related to
scanning in mac80211.  Sujith gives us a small fixup for a regression
in the handling of HT capability bits for ath9k.  Stanislav Yakovlev
is stepping-up as maintainer for the ipw2x00 drivers, so we'll add
him to MAINTAINERS.  Stanislav also gives us a fix for a thinko
that registers the wrong band information for ipw2200 and 802.11a.
Finally, Santosh Nayak adds some simple error checking to orinoco to
avoid some potential NULL pointer dereferences.

Please let me know if there are problems!

Thanks,

John
