That merely depends on the development approach. I saw and reviewed
not one kernel patchsets introducing new drivers and adding features
one after another. Moreover there is no kernel patches requirement
which would constitutes not to do so. In this particular case the
modification isn't complicated at all thus can be reviewed as is.
