Subject: [PATCH 3.13.y-ckt 08/60] mac80211: clear subdir_stations when removing debugfs
Date: Tue, 1 Sep 2015 17:57:14 -0700 [thread overview]
Message-ID: <1441155486-26089-9-git-send-email-kamal@canonical.com> (raw)
In-Reply-To: <1441155486-26089-1-git-send-email-kamal@canonical.com>
3.13.11-ckt26 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Tom Hughes <tom@compton.nu>
commit 4479004e6409087d1b4986881dc98c6c15dffb28 upstream.
If we don't do this, and we then fail to recreate the debugfs
directory during a mode change, then we will fail later trying
to add stations to this now bogus directory:
BUG: unable to handle kernel NULL pointer dereference at 0000006c
