V4L/DVB (3402): Fix handling of VIDIOC_G_TUNER audmode in msp3400
- Fix handling of VIDIOC_G_TUNER audmode in msp3400: audmode is only changed by the user with S_TUNER, never by the driver. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
