V4L/DVB (5183): Fix CC handling in VIDIOC_INT_G_VBI_DATA
When capturing a 60 Hz input the internal field ID is inverted. The VIDIOC_INT_G_VBI_DATA didn't take that into account and so returned XDS instead of CC and vice versa. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
