From 5f9c82c021cca74ad9a2dd48353c01bad567815e Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 5 Sep 2012 12:28:06 -0300 Subject: [PATCH] [media] ivtv: disable a bunch of ioctls that are invalid for the decoder VBI The VBI capture for the decoder (/dev/vbi8) is special in that it captures the VBI stream embedded in an MPEG stream that is being decoded. A lot of the ioctls that would normally be valid have to be disabled since they make no sense for such a device, and v4l2-compliance will complain about that.
