[RFC 16/16] Bluetooth: Remove sk member from struct l2cap_chan

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

 



From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>

Now that the removal of socket usage from l2cap_core.c is done we can
remove sk from struct l2cap_chan since we do not use it anywhere anymore.
