Subject: [PATCH] cw1200: Fix OOPS in monitor mode
Date: Fri, 19 Jul 2013 23:31:27 -0400 [thread overview]
Message-ID: <1374291087-27706-1-git-send-email-pizza@shaftnet.org> (raw)
In monitor mode, priv->vif is NULL, but at one point in the receive path we
blindly attempt to dereference it. Add a test to prevent this.
This patch really needs to go into 3.11-rc
