From 80c42affad970c8ebc5ebec4681aef8dadf21c32 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 21 Jul 2008 09:58:11 +0200 Subject: [PATCH] drivers/net/wireless/ipw2100.c: Release mutex in error handling code The mutex is released on a successful return, so it would seem that it should be released on an error return as well. The semantic patch finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // @@ expression l; @@ mutex_lock(l); ... when != mutex_unlock(l) when any when strict ( if (...) { ... when != mutex_unlock(l) + mutex_unlock(l); return ...; } | mutex_unlock(l); ) // Signed-off-by: Julia Lawall Signed-off-by: John W.
