From e03da047fbec64d868f54e06d2c9b77c37619351 Mon Sep 17 00:00:00 2001 From: Asai Thambi S P Date: Wed, 16 Apr 2014 20:30:16 -0700 Subject: [PATCH] mtip32xx: Remove dfs_parent after pci unregister 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.
