From 2eaf396020555973cad7aa5b517c2418eccbca50 Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Wed, 11 Mar 2009 03:01:02 -0300 Subject: [PATCH] V4L/DVB (11079): au0828: fix panic on disconnect if analog initialization failed If the analog initialization failed to create the video device, we never actually add the entry to the au0828_devlist. Therefore a panic occurs when unregistering the analog subsystem. Make it so we only remove the entry from the list if we added it to the list in the first place.
