From a56635a56f2afb3d22d9ce07e8f8d69537416b2d Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 26 May 2010 05:56:48 +0000 Subject: [PATCH] net/iucv: Add missing spin_unlock Add a spin_unlock missing on the error path. There seems like no reason why the lock should continue to be held if the kzalloc fail. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression E1; @@ * spin_lock(E1,...); <+... when != E1 if (...) { ... when != E1 * return ...; } ...+> * spin_unlock(E1,...); // Signed-off-by: Julia Lawall Signed-off-by: David S.
