[PATCH 1/4] staging: dgap: fix error path

[Sudip Mukherjee <sudipm.mukherjee@gmail.com>]

The code in dgap_stop() is almost a duplicate of the code that will be
executed on pci_unregister_driver(). So the error code was stopping and
unregistering everything twice.

we had a discussion about the init and error path few months back when
another patch was sent. I am not able to find that discussion in
lkml.org
