604What: For VIDIOC_S_FREQUENCY the type field must match the device node's type.
605 If not, return -EINVAL.
606When: 3.2
607Why: It makes no sense to switch the tuner to radio mode by calling
608 VIDIOC_S_FREQUENCY on a video node, or to switch the tuner to tv mode by
609 calling VIDIOC_S_FREQUENCY on a radio node. This is the first step of a
610 move to more consistent handling of tv and radio tuners.

615What: Opening a radio device node will no longer automatically switch the
616 tuner mode from tv to radio.
617When: 3.3
618Why: Just opening a V4L device should not change the state of the hardware
619 like that. It's very unexpected and against the V4L spec. Instead, you
620 switch to radio mode by calling VIDIOC_S_FREQUENCY. This is the second
621 and last step of the move to consistent handling of tv and radio tuners.
