From 27b81bbed881ae93e8c23c216129cdeee86d4051 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 15 May 2010 23:22:55 +0200 Subject: drivers/net/wireless/p54: Use kmemdup Use kmemdup when some other buffer is immediately copied into the allocated region. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression from,to,size,flag; statement S; @@ - to = \(kmalloc\|kzalloc\)(size,flag); + to = kmemdup(from,size,flag); if (to==NULL || ...) S - memcpy(to, from, size); // Signed-off-by: Julia Lawall Signed-off-by: John W.
