[PATCH 17/17] hwmon: (w83773g) Use HWMON_CHANNEL_INFO macro

[Guenter Roeck]

The HWMON_CHANNEL_INFO macro simplifies the code, reduces the likelihood
of errors, and makes the code easier to read.

The conversion was done automatically with coccinelle. The semantic patch
used to make this change is as follows.

@r@

-u32 i[] = {
-  elements,
-  0

-struct hwmon_channel_info j = {
-       .type = ty,
-       .config = i,
-};

@script:ocaml t@

shorter :=
   make_ident (List.hd(List.rev (Str.split (Str.regexp "_") ty)));
elems :=
   make_ident
    (String.concat ","
     (List.map (fun x -> Printf.sprintf "\n\t\t\t   %s" x)
       (Str.split (Str.regexp " , ") elements)))

- &j
+ HWMON_CHANNEL_INFO(shorter,elems)

This patch does not introduce functional changes. Many thanks to
Julia Lawall for providing the semantic patch.
