Message-Id: <1406067727-19683-41-git-send-email-kamal@canonical.com> Date: Tue, 22 Jul 2014 15:20:51 -0700 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Arik Nemtsov <arikx.nemtsov@...el.com>, Emmanuel Grumbach <emmanuel.grumbach@...el.com>, Johannes Berg <johannes.berg@...el.com>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.8 040/116] mac80211: don't check netdev state for debugfs read/write 3.8.13.27 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Arik Nemtsov <arik@...ery.com> commit 923eaf367206e01f22c97aee22300e332d071916 upstream. Doing so will lead to an oops for a p2p-dev interface, since it has no netdev.
