Issue was detected by Coverity. --------------------------- ibsim-0.7/umad2sim/umad2sim.c:151: check_return: Calling "mkdir(dir, 493U)" without checking return value. This library function may fail and return an error code. --------------------------- Also covert the function into a void function, as none of callers checked the return value of make_path.
