This is a minor optimisation to the mcr20a-rf-driver code:
Note that function parameter is pointer. The code is more readable when 'NULL' instead of using '0'.
This is a minor optimisation to the mcr20a-rf-driver code:
1. The function parameter is 'uint8_t *byteArray', (byteArray == NULL) instead of using (byteArray == 0). The code is more readable.
