We used to return negative error codes until commit 23021c21055f ("cnic:
Improve error recovery on bnx2x devices").

To be honest, I like the deliberate "ret = 0;" because this code will
trigger a static checker warning about wrong error codes. Also it looks
wrong to human reviewers. We should probably add a comment:

/* Deliberately returning success */
return 0;
