Until now ST's pinconf_dbg_show() call-back has displayed the PIO alternate function direction, which is only relevant if a pin is operating in an alternate function mode i.e not GPIO mode. If a pin is in GPIO mode its direction is both set and status is obtained by a completely different/unrelated bunch of registers. This change ensures that the correct pin direction is shown, even if a pin is operating in GPIO mode.
