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.
