From: Andrei Emeltchenko <andrei.emeltchenko@xxxxxxxxx> Changing socket lock to L2CAP chan lock in L2CAP code. Needed for implementing protocol above L2CAP without creating sockets. Changes: * PATCHv1: Added extra line (per Gustavo comment) * RFCv6: Same code but patches 2,3 and 4 from RFCv5 are merged together following recommendations from review. * RFCv5: Fixed locking bug in l2cap_data_channel, added locks in l2cap_sock_shutdown function, fixed several styles issues. * RFCv4: Better split patches so they looks more clear and obvious, taking coments about naming change and delete unused vars. See diff change from the previous version below: * RFCv3: Split the big patch to several small (I believe logical) chunks, remove unneded locks from cleanup_listen, use the same arguments for locked/unlocked socket error functions. * RFCv2: Convert l2cap channel list back to mutex from RCU list.
