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). -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
