From 3fadb06daef958d2ae2d3be363a0cfaa92008b52 Mon Sep 17 00:00:00 2001 From: Himangi Saraogi Date: Sat, 9 Aug 2014 22:17:16 +0530 Subject: [PATCH] hdlc: Remove typedefs from struct names The Linux kernel coding style guidelines suggest not using typedefs for structure types. This patch gets rid of the typedefs for fr_hdr and pvc_device. Also, the names of the structs are changed to drop the _t, to make the name look less typedef-like. The following Coccinelle semantic patch detects the case fr_hdr and a similar one detects the case for pvc_device. @tn1@ type td; @@ typedef struct { ... } td; @script:python tf@ td << tn1.td; tdres; @@ coccinelle.tdres = td; @@ type tn1.td; identifier tf.tdres; @@ -typedef struct + tdres { ... } -td ; @@ type tn1.td; identifier tf.tdres; @@ -td + struct tdres Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Signed-off-by: David S.
