From 785955752fde4c555a1d9f74ddfe1f7aca3e0c7f Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 3 Jul 2007 22:28:35 +0200 Subject: [PATCH] ide: Fix a theoretical Ooops case Found by a static analyser. It is in theory possible we dereference dev->id when it has become invalid. Re-order to avoid this.
