V4L/DVB (13996): gspca_stv0680: Fix streaming on vga cameras
Streaming of VGA stv0680 based cams (instead of CIF ones) failed, because we were using the wrong control pipe for certain commands, this patch fixes this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
