[PATCH] Bluetooth: Fix crash when using new BT_PHY option

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

This fixes the invalid check for connected socket which causes the
following trace due to sco_pi(sk)->conn being NULL:

RIP: 0010:sco_sock_getsockopt+0x2ff/0x800 net/bluetooth/sco.c:966

L2CAP has also been fixed since it has the same problem.
