Benoît Dejean noticed that these changes are incorrect, because the code
deals with KeyArr as an array of strings (and a 2D array), while my
changes turn it into a char **. This breaks code like:

Ret = GetVpdKeyArr(pAC, IoC, &KeyArr[0][0], sizeof(KeyArr), &KeyNo);
...
if (SK_STRCMP(KeyStr, KeyArr[Index]) == 0) {
