assert_cfg80211_lock warning with Linux v3.5-8833-g2d53492

[Josh Boyer <jwboyer@redhat.com>]

Hi All,

With the latest Linus tree as of this morning, I'm getting the warning
below continuously.  I've attached the first two instances of it.  The
machine is a Dell XPS 8300 with a BCM4313 wireless chip in it.
Userspace is Fedora 17 and NetworkManager is controlling things though I
don't have it set to connect to any networks.

Please let me know if you've seen this before and if there is more
information I can provide.
