[PATCH] Bluetooth: fix potential NULL ptr deref in dtl1_cs.c::dtl1_hci_send_frame()
There's a problem in drivers/bluetooth/dtl1_cs.c::dtl1_hci_send_frame()
If bt_skb_alloc() returns NULL, then skb_reserve(s, NSHL); will cause a
NULL pointer deref - ouch. If we can't allocate the resources we require
we need to tell the caller by returning -ENOMEM.
Found by the coverity checker as bug #409
