Describe the bug
Latest version of Cppcheck is issuing the following failures for FM:

fsw/src/fm_cmd_utils.c:165:32: style: Variable 'StringLength' is assigned a value that is never used. [unreadVariable]
    int32      StringLength    = 0;
                               ^
fsw/src/fm_tbl.c:74:22: style: Variable 'NameLength' is assigned a value that is never used. [unreadVariable]
    int32 NameLength = 0;
                     ^

To Reproduce
Run the current version of Cppcheck on the current main branch FM source code.

Expected behavior
Cppcheck should pass without raising any errors.
