Summary
s_string checks the explicit declaration of an integer return variable. However, it gives a false warning for functions that have int as a substring in the name, and pass ret as an argument.

E.g.
__wt_call_log_print_return(conn, session, ret, "")
Acceptance Criteria (Definition of Done)

s_string should not give a warning for functions that have int as a substring in the name, and pass ret as an argument.
