I was so excited about finally figuring out how to create and send a 
patch with git, that I forgot to mention that this was a warning seen in 
linux-next, next-20080529.

It was more an experiment in how to send git patches than to "get my 
name in the kernel history", with which most experienced developers seem 
to think us newbies are only concerned.  I keep hearing that testing 
trees and fixing warnings and small bugs is the preferred way to make it 
into development - so I'm giving it a try.

Let me know if there was anything wrong with this submission, or if it 
is too trivial to bother with.
