In particular, when a driver is cloned a new name is selected the new name should follow two rules: It should have the same number of characters as the original driver name and it should not begin or end with a number.
E.g. Calling clones of the TXRX driver TXRA, TXRB, TXRC, etc
E.g. Calling clones of the MODBU driver MODBA, MODBB, MODBC, etc
