Message-Id: <1406067727-19683-8-git-send-email-kamal@canonical.com> Date: Tue, 22 Jul 2014 15:20:18 -0700 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Asai Thambi S P <asamymuthupa@...ron.com>, Jens Axboe <axboe@...com>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.8 007/116] mtip32xx: Remove dfs_parent after pci unregister 3.8.13.27 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Asai Thambi S P <asamymuthupa@...ron.com> 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.
