Some of the internal functions had
int
return type, but they were not returning anything and the places where these functions are called were also not expecting anything from the function.To, simplify such cases, change the function return type to 'void'.
This issue was found using cppcheck tool. It's a low-priority one, since it's in the tests and the functions affected are internal test functions.
