This patch addresses a wrong fix that was done during the review
process. The intention was to substitute "if(ret < 0)" with
"if(ret)". Unfortunately, in this specific file the intended fix did not
meet the code.

Please add a Fixes: tag, even for a patch in net-next

Canonical way of testing an error from ethnl_parse_header_dev_get() is:
if (ret < 0)
return ret;
Please double check for the rest of the patch (ethnl_ops_begin() ... )

Ok, this is what I had originally. I changed that due to another review
comment. I'll revert this change.
