ipw2100: intrusive cleanups, working this time ;-)
From: Pavel Machek
Date: Thu May 12 2005 - 17:53:43 EST
Hi!
There's a lot to clean up in header file, too... And this time it
actually works.
Now, I'd like to clean it a bit more and then submit it to akpm for
-mm series. Will someone hate me for doing that?
