From 2447f2f3c38d3058d50de93df225ee6ad295932b Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 13 Dec 2009 05:35:45 +0000 Subject: [PATCH] drivers/net/cpmac.c: Correct code taking the size of a pointer sizeof(dev->dev_addr) is the size of a pointer. On the other hand, sizeof(pdata->dev_addr) is the size of an array, so use that instead. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression *x; expression f; type T; @@ *f(...,(T)x,...) // Signed-off-by: Julia Lawall Signed-off-by: David S.
