So these hunks made to net/bluetooth/l2cap_core.c:

Doesn't generate the following warnings on your compiler?

net/bluetooth/l2cap_core.c: In function ‘l2cap_recv_frame’:
net/bluetooth/l2cap_core.c:3758:15: warning: ‘sk’ may be used uninitialized in this function
net/bluetooth/l2cap_core.c:3758:15: note: ‘sk’ was declared here
net/bluetooth/l2cap_core.c:3791:15: warning: ‘sk’ may be used uninitialized in this function
net/bluetooth/l2cap_core.c:3791:15: note: ‘sk’ was declared here

I'll fix these up with the obvious fixes, but please be more careful
in the future.

Thanks.
