From c2e813438ef562eee81a42a7fe8f15fd7d9d29b9 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Thu, 12 May 2022 12:05:58 -0700 Subject: [PATCH] hwmon: (ltc2992) 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. @s@ identifier i,j,ty; @@ -struct hwmon_channel_info j = { - .type = ty, - .config = i, -}; @r@ initializer list elements; identifier s.i; @@ -u32 i[] = { - elements, - 0 -}; @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 coccinelle script.
