From e55186fe5fad31962d0ea5ef267bf0c23d98abd4 Mon Sep 17 00:00:00 2001 From: "Antonino A. Daplas" Date: Mon, 26 Jun 2006 00:27:05 -0700 Subject: [PATCH] Detaching fbcon: clean up exit code To detach fbcon, it must also clean up all resources it allocated. This was never done before because fbcon cannot be unloaded.
