hwmon: (raspberrypi-hwmon) Use HWMON_CHANNEL_INFO macro
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@ initializer list elements; identifier i; @@ -u32 i[] = { - elements, - 0 -}; @s@ identifier r.i,j,ty; @@ -struct hwmon_channel_info j = { - .type = ty, - .config = i, -}; @script:ocaml t@ ty << s.ty; elements << r.elements; shorter; elems; @@ 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))) @@ identifier s.j,t.shorter; identifier t.elems; @@ - &j + HWMON_CHANNEL_INFO(shorter,elems) This patch does not introduce functional changes. Many thanks to Julia Lawall for providing the semantic patch. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
