Subject: pull request: wireless-next-2.6 2009-12-08

From: "John W. Linville" <[email-masked]>
Date: Tue, 8 Dec 2009 15:02:24 -0500

Dave,

Here are a couple of dozen more fixes intended for 2.6.33.  They are
mostly small (or at least self-contained), and FWIW about half of
them are specifically for the mwl8k driver.

Please let me know if there are problems!

Thanks,

John
