V4L/DVB (4585): VIDIOC_G_SLICED_VBI_CAP now accepts a v4l2_buf_type, make it IOWR
The VIDIOC_G_SLICED_VBI_CAP needs to receive the v4l2_buf_type field before it can return a result. Hence this ioctl must be IOWR, not IOR. Since this ioctl is still marked experimental we can make this change. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
