The minimum and maximum vblanking can change when a new format is applied to the sensor subdevice, so be sure to retrieve up-to-date values. The V4L2Device acquires the new updateControlInfo() method to perform this function, and which the CameraSensor calls automatically if its setFormat method is used to update the sensor. However, not all pipeline handlers invoke the setFormat method directly, so the new method must be made publicly available for pipeline handlers to call if they need to.
