Subject: [PATCH 15/26] atl1: tidy up ring management
Date: Mon, 31 Dec 2007 19:59:53 -0600 [thread overview]
Message-ID: <1199152804-3889-16-git-send-email-jacliburn@bellsouth.net> (raw)
In-Reply-To: <1199152804-3889-1-git-send-email-jacliburn@bellsouth.net>
From: Jay Cliburn <jacliburn@bellsouth.net>
Check for null pointers and such in ring handling functions. Make
needlessly global functions static. Clean up some comments and indentation.
Signed-off-by: Jay Cliburn <jacliburn@bellsouth.net>
