From 9895c503ef5b32c1ff4c4c224d6e8db2935dc3c0 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 13 Jan 2014 17:17:24 +0100 Subject: ksz884x: delete useless variable Delete a variable that is at most only assigned to a constant, but never used otherwise. In this code, it is the variable result that is used for the return code, not rc. A simplified version of the semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // @@ type T; identifier i; constant c; @@ -T i; <... when != i -i = c; ...> // Signed-off-by: Julia Lawall Signed-off-by: David S.
