It's only a warning, not an error.

And it doesn't make sense to open bugs for every single compile warning in the
kernel.

Comment 2 Stefan Richter 2006-10-14 03:17:32 UTC

Fix for the warnings was posted on 2006-10-10:
http://groups.google.com/group/fa.linux.kernel/browse_frm/thread/fa5fc47f1216d4d0/d0ccd92efc18b0a8?tvc=1
and will appear in -mm soon.
