It looks like the patches are assuming the regulator core,
doesn't free the GPIO on an error, however that is not true in
all cases. If only a single regulator has requested the GPIO then
all the error paths after the call to regulator_ena_gpio_request
in regulator_register will free the GPIO. Although this is not the
case if more than one regulator has requested the GPIO.
Thanks,
charles
