From b145edcd1642d55a8eb7d08c954b815cb1478981 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Thu, 10 Oct 2013 09:47:54 -0700 Subject: [PATCH] Bluetooth: Use hci_conn_num() for checking number of LE connections When checking for the current number of LE connections, use hci_conn_num() function instead of a full blown lookup within the connection hash or direct access of the counters. In the case of re-enabling advertising, it is more useful to check for any connection attempt or existing connection.
