From: Asai Thambi S P <asamymuthupa@micron.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit af5ded8ccf21627f9614afc03b356712666ed225 upstream.
In module exit, dfs_parent and it's subtree were removed before unregistering with pci. When debugfs entry for each device is attempted to remove in pci_remove() context, they don't exist, as dfs_parent and its children were already ripped apart.
Modified to first unregister with pci and then remove dfs_parent.
