From e9b15b54d3646108bbd3e054158b402025d3e704 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 23 Nov 2005 13:37:44 -0800 Subject: [PATCH] [PATCH] Fix crash in unregister_console() If unregister_console() is inadvertently called while no consoles are registered, it will crash trying to dereference NULL pointer. It is necessary to fix that because register_console() provides no indication that it actually registered the console passed in. In fact, it may well decide not to register it based on various things... (akpm: It'd be better to make register_console() return something and fix the callers. All 106 of them...)
