Also removed the bogus zeroing of fmt.sliced when setting up raw VBI. Switching between raw and sliced VBI changed in 2.6.28 and this memset should have been removed at that time. It was never noticed because the bridge driver will fill in the fmt.vbi values anyway. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

/* ENABLE_PVR150_WORKAROUND activates a workaround for a hardware bug that is
|
|
present in Hauppauge PVR-150 (and possibly PVR-500) cards that have
|
|
certain NTSC tuners (tveeprom tuner model numbers 85, 99 and 112). The
|
|
audio autodetect fails on some channels for these models and the workaround
|
|
is to select the audio standard explicitly. Many thanks to Hauppauge for
|

providing this information. */
