[PATCH] sound: oss: uart401: Remove typedef uart401_devc

From: Himangi Saraogi
Date: Wed Aug 06 2014 - 08:47:37 EST


The Linux kernel coding style guidelines suggest not using typedefs
for structure types. This patch gets rid of the typedef for uart401_devc.

The following Coccinelle semantic patch detects the case.

@tn@
identifier i;
type td;
@@

-typedef
struct i { ... }
-td
;

@@
type tn.td;
identifier tn.i;
@@

-td
+ struct i
