[driver-discuss] A question about the validity of the Device Driver Tutorial?

Hi again,

Lower in the same function, why is ddi_remove_minor_node() called when
the corresponding ddi_create_minor_node() fails?

    if (ddi_create_minor_node(dip, QOTD_NAME, S_IFCHR,
                              instance, DDI_PSEUDO, 0) 
        != DDI_SUCCESS) {
      cmn_err(CE_WARN, "Cannot create minor node for %d",
              instance);
      ddi_soft_state_free(dip, instance);
      ddi_remove_minor_node(dip, NULL);
      return (DDI_FAILURE);
    }
