If this was called with a NULL "dev" then it lead to a NULL dereference when we called dev_WARN(). I have changed it to WARN_ON() so that we get a stack dump and can fix the caller. The rest of this patch is just cleanup like returning directly instead of having do-nothing gotos. Using descriptive labels instead of GW-BASIC style "err0" and "err1". I also flipped the order of put_device() and ida_remove() so they are a mirror reflection of the order they were allocated.
