From 5a5a4e16fa19fa3789398e8c707168b7da718b64 Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Wed, 11 Mar 2009 03:00:55 -0300 Subject: [PATCH] V4L/DVB (11073): au0828: disable VBI code since it doesn't yet work Since the VBI support is not yet working for the au0828, don't advertise the capability or create the /dev/vbi device.
