[BUG] BlueTooth socket busted in 2.6.0-test5

	Hi,

	This is self explanatory :

-----------------------------------------------------------

	Basically, the socket is already owned by the 'bluetooth'
module in bt_sock_alloc(), and the 'l2cap' module try to change the
ownersip to itself in l2cap_sock_alloc(). The socket layer doesn't
like it. At least, that's the way I read it.
	Without the ability to open BT socket, BT is pretty much
useless.

	Good luck...

	Jean
