for -rc we usually want the smallest patch needed to fix the issue. That
would be the two line if() condition. If converting to
of_device_get_match_data() is about the same (2 or 3 lines), then it
should be fine; but as a general rule of thumb: we don't fix and
cleanup/refactor on the same patch unless strictly necessary.
