From 55ebcc38a5f6d40e4c41447e413ef842b803980f Mon Sep 17 00:00:00 2001 From: Arnaud Patard Date: Sat, 16 Sep 2006 12:15:36 -0700 Subject: [PATCH] IPMI: Fix oops on ipmi_msghandler removal for non ipmi systems When the ipmi_si module is loaded on a system without any ipmi device, it fails with nodev. It would be fine if all resources were freed. A call to device_unregister() is missing, resulting to a oops when you remove the ipmi_msghandler.

Fix the code to handle this. This was tested by setting the flags by hand after they were fetched.
