From 791d60f71a8d743df17a5029bb080a24afc4fff6 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 14 May 2013 22:24:44 +0300 Subject: [PATCH] Bluetooth: Refactor L2CAP connect rejection to its own function We'll need to have a separate code path for LE based connection rejection so it's cleaner to move out the response construction code into its own function (and later a second one for LE).
