---------------------+--------------------
 Reporter:  gedare   |      Owner:
     Type:  defect   |     Status:  new
 Priority:  normal   |  Milestone:  4.11.1
Component:  General  |    Version:  4.11
 Severity:  normal   |   Keywords:
---------------------+--------------------
 rtems_gpio_enable_interrupt() in libbsp/shared/gpio.c should free the
 interrupt_state in case of a failure to
 rtems_gpio_interrupt_handler_install.

 Also, the "if ( threaded_handling ) {" section the two error paths that
 return RTEMS_UNSATISFIED should undo the
 rtems_gpio_interrupt_handler_install of the pin handler and also free the
 interrupt_state.
