No! I hate when people initialize error values like that, because it is so easy to miss the case and end up with wrong value. If the original version of the driver did not initialize it to 0 compiler would warn the author and the error would not make it into the mainline to begin with.
Please explicitly assign error codes in error handling path.
Thanks.
