From f8218dc6605a7b2af843f9ff5d66229a4a0b1c45 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 16 Jul 2014 11:56:08 +0300 Subject: [PATCH] Bluetooth: Track number of LE slave connections Most (probably all) controllers can only deal with a single slave LE connection at a time. This patch adds a counter for such connections so that the number can be quickly looked up without iterating the connections list.
