John W. Linville - Dec. 21, 2009, 7:16 p.m.
Dave,

Here is another big batch of fixes intended for 2.6.33.  They are mostly
driver fixes, along with a couple of small ones for mac80211.  I don't
think there is anything controverisal here.

Please let me know if there are problems!

Thanks,

John

P.S.  This re-adjusts after the rebasing confusion from this weekend.
The sliver lining is that it allowed me to drop a patch which in the
interim revealed itself to be broken in wireless-testing.

Pulled, thanks John.  I'll push it back out after my build
checks complete.
