pullreq: wireless-next-2.6 2010-03-03

From: John W. Linville
Date: Wed Mar 03 2010 - 16:30:54 EST

Dave,

Here is another quick batch intended for 2.6.34. Included are a
USB ID, some small fixes, and a few (for async firmware loading and
KEY_RFKILL) that depended on patches that weren't in the net-next-2.6
tree until after the merge window opened.

Please let me know if there are problems!

Thanks,

John
