From c6cb13aead3a3cf5bd3e2cfa945602d5cd7825cd Mon Sep 17 00:00:00 2001 From: Wim Van Sebroeck Date: Wed, 26 Dec 2007 20:32:51 +0000 Subject: [WATCHDOG] misc_register patch Make sure that we first do a register_reboot_notifier before we do a misc_register. A misc_register opens the interface to userspace and it's best to do this as the last action.
