Bluetooth: Make __l2cap_wait_ack more efficient
Use chan->state instead of chan->conn because waiting for ACK's is only possible in the BT_CONNECTED state. Also avoids reference to the conn structure so makes locking easier. Only call __l2cap_wait_ack() when the needed condition of chan->unacked_frames > 0 && chan->state == BT_CONNECTED is true and convert the while loop to a do while loop. __l2cap_wait_ack() change the function prototype to pass in the chan variable as chan is already available in the calling function l2cap_sock_shutdown(). Avoids locking issues. Signed-off-by:Dean Jenkins <Dean_Jenkins@mentor.com> Signed-off-by:
