The idea of pinctrl_get_select_default() is (as you could guess from it's name) to get a pin ctrl handle and select the default state. The return code from that function tells you whether that was successful or not. It does *NOT* tell you to go and look up GPIO values if it wasn't! Then the function would be named bool pinctrl_is_used_on_this_system().
