Seems a good idea to me.

I don't see much sense on allowing v4l2-common being in-kernel, while having
I2C as module. Also, creating a separate module for just a single function
seems to be overkill.
IMO, in this specific case, v4l2-common should also be a module. Not sure,
however,the better syntax on Kconfig. Once, someone suggested a very weird
syntax, like:
depends on I2C if I2C
Cheers,
