Causing build error [1], there are various formatting used for printing port_id
[2], do we need this %hhu accuracy, I am for %u since port_id is an unsigned
value result should be same.

[1]
        printf("Port %hhu EEPROM:\n", port_id);
                     ~~~~             ^~~~~~~
                     %hu

[2]
%d, %u, %PRIu8 [wrong], %PRIu16
