commit b49ba04a3a0382e7314d990707c21094c410425a

Dave,

Here are a couple of "one-liner" fixes intended for 3.3.

A mac80211 fix from Eliad Peller fixes a regression from an earlier
patche that accidentally removed a necessary line of code.  The other
one from Eliad adds an overlooked assignment necessary for proper
management of some state information.  Finally, the fix from Johannes
moves an unlock to include an additional operation within the critical
section.

Pleae let me know if there are problems!

Thanks,

John
