Depending on which sensor is used, the format from the sensor is different. The format.code inside the dev struct holds this information. The enum mbus and enum frame sizes need to take into account both type of sensors, not just the color one. To solve this, use the format.code in these functions instead of the hardcoded bayer color format (which is only used for mt9v032).
