Why the difference for the two drivers? Either the HW is compatible with
all 3 of 114/30/20 (in which case you only need list 114/20 in the
compatible value), or it's not compatible with either 30/20, since we
already know that 30/20 are compatible with each-other (in which case
you should only list 114 in the compatible property).
