sudip,thanks for your comments.while I agree that my patch does the same thing twice,I see that a similar thing is being done in the failure path of the dgap_init_module().I am referring to the goto err_unregister path where the pci_unregister_driver() and dgap_stop() are invoked in succession.Going by your argument,should we remove the redundant cleanup done in the dgap_stop() function.
