Subject: [PATCH net-next 01/15] ethtool: rename ethnl_parse_header() to
ethnl_parse_header_dev_get()
Andrew Lunn pointed out that even if it's documented that
ethnl_parse_header() takes reference to network device if it fills it
into the target structure, its name doesn't make it apparent so that
corresponding dev_put() looks like mismatched.
Rename the function ethnl_parse_header_dev_get() to indicate that it
takes a reference.
