From f5011f9fc287a7894abf83c70bebdbf905dd0f78 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sun, 31 Mar 2019 10:53:48 -0700 Subject: [PATCH] hwmon: (lm95241) 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.
