If I understand what you're saying, ov2640 and ovv7670 are both video drivers but they have shared functionality. If the shared functionality is in the form of controlling say an i2c device of some sorts then you should implement that functionality as a subdev. Otherwise, you should extract the shared functionality into its own module that can be utilized by both drivers (there are many examples of this within the kernel).
